Bulk-library routines use a CS_BLKDESC, or bulk descriptor structure. The bulk descriptor is the control structure for bulk copy operations.
An application calls blk_alloc to allocate a CS_BLKDESC structure.
After completing a bulk copy operation, an application frees a CS_BLKDESC by calling blk_drop.
Bulk-Library routines are documented in the Open Client and Open Server Common Libraries Reference Manual.
