Remove notification entries from list
#include <sys/iofunc.h> void iofunc_notify_remove( resmgr_context_t * ctp, iofunc_notify_t * nop );
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The iofunc_notify_remove() function removes all of the entries associated with the current client from the notification list passed in nop. The client information is obtained from the ctp.
If the ctp pointer is NULL, then all of the notify entries will be removed. A resource manager generally calls this function, with NULL as the ctp in the close_ocb callout, to clean up all handles associated with this connection. If the handles are shared between several connections, then the ctp should be provided to clean up after each client.
