 * When receiving commands or data sets:
 * If the parameter blockMode is DIMSE_BLOCKING, the DIMSE routine
 * will wait until a response arrives before returning.
 * If the parameter blockMode is DIMSE_NONBLOCKING then the DIMSE routine
 * will wait at most timeout seconds for a response and if no response arrives
 * will return DIMSE_NODATAAVAILABLE.  In both cases waiting will be
 * interupted by association release, and abort messages, or network

/*
** CVS Log
** $Log: dimse.h,v $
** Revision 1.22  2010-10-14 13:17:22  joergr
** Updated copyright header. Added reference to COPYRIGHT file.
**
** Revision 1.21  2009-11-18 11:53:58  uli
** Switched to logging mechanism provided by the "new" oflog module.
**
** Revision 1.20  2009-08-04 10:07:48  joergr
** Added optional parameter to printCStore() functions that allows for printing
** the Presentation Context ID.
**
** Revision 1.19  2007/07/12 12:18:00  onken
** Added status codes and corresponding printing routines for DIMSE-N.
**
** Revision 1.18  2006/08/15 16:04:29  meichel
** Updated the code in module dcmnet to correctly compile when
**   all standard C++ classes remain in namespace std.
**
** Revision 1.17  2005/12/08 16:02:21  meichel
** Changed include path schema for all DCMTK header files
**
** Revision 1.16  2005/11/22 16:44:44  meichel
** Added option to movescu that allows graceful handling of Move SCPs
**   that send illegal datasets following pending C-MOVE-RSP messages.
**
** Revision 1.15  2005/02/22 09:40:55  meichel
** Fixed two bugs in "bit-preserving" Store SCP code. Errors while creating or
**   writing the DICOM file (e.g. file system full) now result in a DIMSE error
**   response (out of resources) being sent back to the SCU.
**
** Revision 1.14  2003/08/27 15:03:33  meichel
** Changed anonymous struct typedefs into struct declarations
**
** Revision 1.13  2002/09/10 16:00:47  meichel
** Added global flag dcmMaxOutgoingPDUSize that allows to restrict the maximum
**   size of outgoiung P-DATA PDUs to a value less than the maximum supported by
**   the remote application entity or this library.  May be useful if there is an
**   interaction between PDU size and other network layers, e. g. TLS, IP or
**   below.
**
** Revision 1.12  2002/08/27 17:00:59  meichel
** Initial release of new DICOM I/O stream classes that add support for stream
**   compression (deflated little endian explicit VR transfer syntax)
**
** Revision 1.11  2001/10/12 10:18:26  meichel
** Replaced the CONDITION types, constants and functions in the dcmnet module
**   by an OFCondition based implementation which eliminates the global condition
**   stack.  This is a major change, caveat emptor!
**
** Revision 1.10  2000/12/15 13:28:16  meichel
** Global flag to enable/disable workaround code for some buggy Store SCUs
**   in DIMSE_storeProvider().  If enabled, an illegal space-padding in the
**   Affected SOP Instance UID field of the C-STORE-RQ message is retained
**   in the corresponding C-STORE-RSP message.
**
** Revision 1.9  2000/06/07 08:57:52  meichel
** dcmnet DIMSE routines now allow to retrieve raw command sets as DcmDataset
**   objects, e.g. for logging purposes. Added enhanced message dump functions.
**
** Revision 1.8  2000/01/31 17:14:17  meichel
** ntroduced new flag g_dimse_save_dimse_data. If enabled, all DIMSE messages
** and data sets sent or received are stored in files.
** This facilitates debugging of DIMSE problems.
**
** Revision 1.7  1999/04/19 08:36:48  meichel
** Added support for C-FIND-CANCEL/C-MOVE-CANCEL in DIMSE_storeUser().
**
** Revision 1.6  1998/08/10 08:53:40  meichel
** renamed member variable in DIMSE structures from "Status" to
**   "DimseStatus". This is required if dcmnet is used together with
**   <X11/Xlib.h> where Status is #define'd as int.
**
** Revision 1.5  1998/06/29 12:14:26  meichel
** Removed some name clashes (e.g. local variable with same
**   name as class member) to improve maintainability.
**   Applied some code purifications proposed by the gcc 2.8.1 -Weffc++ option.
**
** Revision 1.4  1997/07/21 08:40:10  andreas
** - Replace all boolean types (BOOLEAN, CTNBOOLEAN, DICOM_BOOL, BOOL)
**   with one unique boolean type OFBool.
**
** Revision 1.3  1997/05/23 10:47:06  meichel
** Major rewrite of storescp application. See CHANGES for details.
** Changes required to interfaces of some DIMSE functions.
**
** Revision 1.2  1996/04/25 16:06:28  hewett
** Replaced declarations of DIC_UL with unsigned long.
**
** Revision 1.1.1.1  1996/03/26 18:38:45  hewett
** Initial Release.
