If you plan to use bulk copy routines, link in the libsybblk library. If you plan to use bulk-copy routines in a threaded applications, link in the libsybblk_r library.
To link in the bulk-copy library:
In non-threaded applications, add -lsybblk before -lsybct on the link line.
In multithreaded applications, add -lsybblk_r before -lsybct_r on the link line.
See the Open Client and Open Server Common Libraries Reference Manual for more information on bulk copying.
