pfm_inhibit_faults(3ncs)												  pfm_inhibit_faults(3ncs)

Name
       pfm_inhibit_faults - inhibit asynchronous faults

Syntax
       #include <idl/c/base.h>
       #include <idl/c/pfm.h>

       void pfm_$inhibit_faults()

Description
       The  routine prevents asynchronous faults from being passed to the calling process.  While faults are inhibited, the operating system holds
       at most one asynchronous fault.	Consequently, a call to can result in the loss of some signals.  It is good  practice  to  inhibit  faults
       only when absolutely necessary.	This call has no effect on the processing of synchronous faults such as floating-point and overflow excep-
       tions, access violations, and so on.

       void pfm_$enable_faults()

Description
       The routine enables asynchronous faults after they have been inhibited by a call to causes the operating system to pass asynchronous faults
       on to the calling process.

       While faults are inhibited, the operating system holds at most one asynchronous fault.  Consequently, when returns, there can  be  at  most
       one  fault waiting on the process.  If more than one fault was received between routines to and the process receives the first asynchronous
       fault received while faults were inhibited.

Diagnostics
       This section lists the status codes for errors returned by this routine.

       pfm_$bad_rls_order  Attempted to release a clean-up handler out of order.

       pfm_$cleanup_not_found
			   There is no pending clean-up handler.

       pfm_$cleanup_set    A clean-up handler was established successfully.

       pfm_$cleanup_set_signalled
			   Attempted to use pfm_$cleanup_set as a signal.

       pfm_$invalid_cleanup_rec
			   Passed an invalid clean-up record to a routine.

       pfm_$no_space	   Cannot allocate storage for a clean-up handler.
