* $Log: qblastapi.h,v $
* Revision 1.10  2003/01/15 22:04:50  madden
* Moved BLASTGetSeqAnnotByRIDEx from internal
*
* Revision 1.9  2003/01/02 15:06:48  boemker
* Wrote BLASTGetQueryBioseqByRIDEx that extends behavior of
* BLASTGetQueryBioseqByRID by returning the Bioseq for a particular query
* (rather than always returning the Bioseq for the first query.  Modified
* BLASTGetQueryBioseqByRID to use BLASTGetQueryBioseqByRIDEx.  Wrote
* BLASTGetQuerySummary to return information about a query.
*
* Revision 1.8  2001/02/21 22:07:34  lavr
* Changes for use new CONN interface
*
* Revision 1.7  2000/12/06 17:53:46  madden
* Add prototype for QBBioseqToFasta
*
* Revision 1.6  2000/11/07 21:57:18  shavirin
* Added definition of the new function BLASTGetQueryBioseqByRID()
* Added few connection -oriented defines in the header.
*
* Revision 1.5  2000/07/19 15:17:15  shavirin
* Added loging for this file.
