Derived classes can add the presentation contexts they want to support, set further parameters (port, peer hostname, etc. as desired) and then call DcmSCP's listen() method to start the server. For incoming associations and DIMSE messages, a derived class can define the behaviour of the server. The DcmSCP base class is capable of responding to C-ECHO requests (Verification SOP Class).

| xferSyntaxes | [in] List of transfer syntaxes (UIDs) that should be supported for the given abstract syntax name | |
| role | [in] The role to be negotiated | |
| profile | [in] The profile the abstract snytax should be added to. The default is to add it to the DcmSCP's internal standard profile called "DEFAULT". |
| void DcmSCP::setPort | ( | const Uint16 | port | ) |
Set SCP's TCP/IP listening port.
| port | [in] The port number to listen on. Note that usually on Unix-like systems only root user is permitted to open ports below 1024. |
| void DcmSCP::setAETitle | ( | const OFString & | aetitle | ) |
Set AETitle of the server.
| aetitle | [in] The AETitle of the server. By default, all SCU association requests calling another AETitle will be rejected. This behaviour can be changed by using the setRespondWithCalledAETitle() method. |
| void DcmSCP::setRespondWithCalledAETitle | ( | const OFBool | useCalled | ) |
Set SCP to use the called AETitle from the SCU request for the response, i.e. the SCP will always respond with setting it's own name to the one the SCU used for calling.
Overrides any AETitle eventually set with setAETitle().
| useCalled | [in] If OFTrue, the SCP will use the called AE title from the request for responding. DcmSCP's default is OFFalse. |
| virtual OFCondition DcmSCP::loadAssociationCfgFile | ( | const OFString & | assocFile | ) | [virtual] |
Loads association configuration file.
| assocFile | [in] The filename of the association configuration to be loaded. The association configuration file must be valid for an SCP. |
| virtual OFCondition DcmSCP::setAndCheckAssociationProfile | ( | const OFString & | profileName | ) | [virtual] |
If an association profile should be selected, either by loading an associaton configuration file or using the addAbstractSyntax() function, one of those can be selected and checked for validity using this method.

Set maximum PDU size the SCP is able to receive.
This size is sent in associaton response message to SCU.

| OFCondition DcmSCP::enableMultiProcessMode | ( | int | argc = 0, |
|
| char * | argv[] = NULL | |||
| ) |
Enable multi-process mode for SCP.
For every incoming association, a new process is started. For Unix this is done with the fork() command that creates a copy of the process running and continues executing the code after the fork() called seamlessy. For Windows CreateProcess() is used given the commandline specified in the function's parameters. The created process is handled a copy of the open TCP/IP connection and then is responsible for handling the association. After process fork/creation, DcmSCP is ready for listening to new connection requests.
| argc | [in] Number of commandline arguments (only Windows) | |
| argv | [in] Command line (only Windows) |
| void DcmSCP::setMaxAssociations | ( | const Uint16 | maxAssocs | ) |

| void DcmSCP::setDIMSEBlockingMode | ( | const T_DIMSE_BlockingMode | blockingMode | ) |
Set whether DIMSE messaging should be blocking or non-blocking.
In non-blocking mode, the networking routines will wait for DIMSE messages for the specified DIMSE timeout time, see setDIMSETimeout() function. In blocking mode, no timeout is set but the operating system's network routines will be used to read from the socket for new data. In the worst case, this may be a long time until that call returns. The default of DcmSCP is blocking mode.
| blockingMode | [in] Either DIMSE_BLOCKING for blocking mode or DIMSE_NONBLOCKING for non-blocking mode |
| void DcmSCP::setDIMSETimeout | ( | const Uint32 | dimseTimeout | ) |
Set the timeout to be waited for incoming DIMSE message packets.

| void DcmSCP::setACSETimeout | ( | const Uint32 | acseTimeout | ) |
Set the timeout used during ACSE messaging protocol.
| acseTimeout | [in] ACSE timeout in seconds. |
| void DcmSCP::setVerbosePCMode | ( | const OFBool | mode | ) |
Set whether to show presentation contexts in verbose or debug mode.
| mode | [in] Show presentation contexts in verbose mode if OFTrue. By default, the presentation contexts are shown in debug mode. |

Returns TCP/IP port number SCP listens for new connection requests.
| const OFString& DcmSCP::getAETitle | ( | ) | const |
Returns SCP's own AE title.
Only used if the SCP is not configured to respond with the called AE Title the SCU uses for association negotiation, see setRespondWithCalledAETitle().
| OFBool DcmSCP::getRespondWithCalledAETitle | ( | ) | const |

Returns whether SCP is running in single or multi-process mode.
| Uint16 DcmSCP::getMaxAssociations | ( | ) | const |
Returns number of maximum simultanous connections permitted.
Only makes sense for Unix operating systems. For Windows, the number of maximum connections is either "unlimited" or 1. Use getSingleProcess() in that case to find out if SCP is permitting more than one connection.
| T_DIMSE_BlockingMode DcmSCP::getDIMSEBlockingMode | ( | ) | const |
Returns whether receiving of DIMSE messages is done in blocking or unblocking mode.
| Uint32 DcmSCP::getDIMSETimeout | ( | ) | const |
Returns DIMSE timeout (only applicable in blocking mode).
| Uint32 DcmSCP::getACSETimeout | ( | ) | const |
Returns ACSE timeout.
| OFBool DcmSCP::getVerbosePCMode | ( | ) | const |

If in multi-process mode, the "father" process should always return false here, because connection is always handled by child process.
| Uint16 DcmSCP::numAssociations | ( | ) | const |
Returns number of associations currently running.
Only applicable in Unix-like operating systems. Can only be greater than one when running in multi-process mode.
| OFString DcmSCP::getCalledAETitle | ( | ) | const |

| ) | [protected, virtual] |
Handle incoming command set and react accordingly, e.g. sending response via DIMSE_sendXXXResponse().
The standard handler only knows how to handle an Echo request by calling handleEchoRequest(). This function is most likely to be implemented by a derived class implementing a specific SCP behaviour.

| DcmDataset *& | reqDataset, | |||
| Uint16 & | eventTypeID | |||
| ) | [protected, virtual] |
Receives N-EVENT-REPORT request on the currently opened association and sends a corresponding response.

| const OFString & | calledAE | |||
| ) | [protected, virtual] |
Function that checks for each association request, whether the combination of calling and called AE title proposed by the SCU is accepted.
The standard behaviour is to either accept any AE title (if the corresponding option is set) or to only accept the one set with setAETitle(). In the former case, the function also adopts the SCP's AETitle to the one used by the SCU. The method can be overwritten to have full control about which AE title combinations are accepted by the SCP.

| calledAE | [in] The AE title the SCU uses as Called AE Title |
| virtual OFCondition DcmSCP::waitForAssociation | ( | T_ASC_Network * | network | ) | [protected, virtual] |
This function takes care of receiving, negotiating and accepting/refusing an association request.
Additionally, if negotiation was successful, it handles any incoming DIMSE commands by calling handleAssociation(). An error is only returned, if something goes wrong. Therefore, refusing an association because of wrong application context name or no common presentation contexts with the SCU does NOT lead to an error.
| network | [in] Contains network parameters |
| virtual void DcmSCP::cleanChildren | ( | ) | [protected, virtual] |
This function takes care of removing items referring to (terminated) subprocess from the table which stores all subprocess information.
This function does not make sense for Windows operating systems where the SCP does not have any control over additionally created processes.
| virtual OFCondition DcmSCP::negotiateAssociation | ( | ) | [protected, virtual] |
This function checks all presentation contexts proposed by the SCU whether they are supported or not.
It is not an error if no common presentation context could be identified with the SCU; only issues like problems in memory management etc. are reported as an error. This function does not send a response message to the SCU. This is done in other functions.
| virtual void DcmSCP::addProcessToTable | ( | int | pid | ) | [protected, virtual] |
This function adds a process to the table that stores process information (only relevant for multi-process mode under Unix-like systems).

Note that the value for element (0000,0900) is not contained in this return value but in internal msg. For details on the structure of this object, see DICOM standard part 7, annex C). | |
| commandSet | [out] If this parameter is not NULL, it will return a copy of the DIMSE command which was received from the other DICOM application. The caller is responsible to de-allocate the returned object! | |
| timeout | [in] If this parameter is not 0, it specifies the timeout (in seconds) to be used for receiving the DIMSE command. Otherwise, the default timeout value is used (see setDIMSETimeout()). |

DcmAssociationConfiguration* DcmSCP::m_assocConfig [private] |
Association configuration.
May be filled from association configuration file or by adding presentation contexts by calling addPresentationContext() (or both)
OFString DcmSCP::m_assocCfgProfileName [private] |
OFString DcmSCP::m_aetitle [private] |
AETitle to be used for responding to SCU (default: DCMTK_SCP).
This value is not evaluated if the the SCP is configured to respond to any assocation requests with the name the SCU used as Called AE Title (which is the SCP's default behaviour); see setRespondWithCalledAETitle().
Uint32 DcmSCP::m_maxReceivePDULength [private] |
OFBool DcmSCP::m_singleProcess [private] |
Indicates if SCP is run in single process mode or not.
In multi-process mode, the SCP starts a new process for any incoming association request. The association is then completetly handled by the "child" process while the parent process keeps listening for new associations. Under Unix, multi-process mode uses the fork command to spawn a process which is an exact copy of the parent and continues code execution after the fork command. For Windows, the programmer of the derived class is responsible for setting the command line needed for the internal "CreateProcess" call. The commandline arguments are specified with function enableMultiProcessMode().
Uint16 DcmSCP::m_maxAssociations [private] |
T_DIMSE_BlockingMode DcmSCP::m_blockMode [private] |
Blocking mode for DIMSE operations.
If DIMSE non-blocking mode is enabled, the SCP is wating for new DIMSE data a specific (m_dimseTimeout) amount of time and then returns if not data arrives. In blocking mode the SCP is calling the underlying operating system function for receiving data from the socket directly, which may return after a very long time, depending on the system's network configuration.
