* Modifications:
* --------------------------------------------------------------------------
* Date     Name         Description of modification
* -------- -----------  -----------------------------------------------------
* 12-10-93 Schuler      Major Revision.  New APIs include:  ErrPostEx,
*                       ErrSetMessageLevel, ErrSetFatalLevel,
* 10-20-94 Schuler      Rearranged some things to make CodeCenter happy
* 11-18-94 Schuler      Changed return type of Get/SetXXXLevel() family
*                       of functions from int to ErrSev to eliminate warnings
*
* $Log: ncbierr.h,v $
* Revision 6.8  2006/07/13 17:10:36  bollin
* use Uint4 instead of Uint2 for itemID values
*
* Revision 6.7  2001/07/12 21:58:03  vakatov
* Introduced #NLM_NO_TRACE (define it if you need to prohibit macro #TRACE)
*
* Revision 6.6  2001/02/08 22:27:04  vakatov
* + Nlm_CallErrHandlerOnly() -- to allow processing of posted
* err.messages by the hook only.
*
* Revision 6.5  1999/10/01 14:41:39  kans
* added SEV_REJECT between SEV_ERROR and SEV_FATAL
*
* Revision 6.4  1999/05/20 20:07:03  sirotkin
* ErrPostItem bullet proofed as per vakatov
*
* Revision 6.3  1998/10/22 16:52:41  shavirin
* Added function *Nlm_GetErrLongText able to retrieve long error messages
*
* Revision 6.2  1997/11/04 19:08:36  ostell
* added ErrGetUserStrings() to eliminate direct access to ErrDesc.userstr
* so this could become a thread specific chain
*
* Revision 6.1  1997/08/27 20:40:27  kans
* added ErrPathReset
*
* Revision 6.0  1997/08/25 18:15:27  madden
* Revision changed to 6.0
*
* Revision 5.2  1996/12/03 21:48:33  vakatov
* Adopted for 32-bit MS-Windows DLLs
*
 * Revision 5.1  1996/11/25  19:03:33  vakatov
 * Moved 'busy' flag to the one-per-thread ErrMsgRoot() structure
 * (it was static before and caused a lot of MT-mess).
 * Added Nlm_ErrGetLogfile() and Nlm_AbnormalExitPure() f-protos.
 * Added ASSERT_HARD() and VERIFY_HARD() macros calling
 * Nlm_AbnormalExitPure() instead of Nlm_AbnormalExit().
 *
 * Revision 5.0  1996/05/28  13:18:57  ostell
 * Set to revision 5.0
 *
 * Revision 4.0  1995/07/26  13:46:50  ostell
 * force revision to 4.0
 *
 * Revision 2.30  1995/05/15  18:45:58  ostell
 * added Log line
