Disassociate a signaling process from the signaling interface.
The signaling interface library (libsl.a).
#include <slsigpr.h> ... SL_RET_CODE sl_close ( SL_HANDLE sl_handle );
This subroutine must be issued by a signaling process when it has finished processing, to close the signaling interface. The process must provide the signaling handle that was returned when it opened the signaling interface. Once the signaling interface is closed, the signaling handle is no longer valid, and the signaling interface subroutines that require a handle cannot be called.
