pfm_$inhibit − inhibit asynchronous faults

SYNOPSIS (C)

#include <idl/c/base.h>
#include <ppfm.h>

void pfm_$inhibit(void);

SYNOPSIS (PASCAL)

procedure pfm_$inhibit;

Remarks

To view this manual entry via the man(1) command, use the function name shown above without the “$” character. 

DESCRIPTION

pfm_$inhibit() prevents asynchronous faults from being passed to the calling process.  While faults are inhibited, the operating system holds at most one asynchronous fault.  Consequently, a call to pfm_$inhibit() can result in the loss of some signals.  For that and other reasons, it is good practice to inhibit faults only when absolutely necessary. 

See the reference description of pfm_$init() for a list of the C signals that the PFM package intercepts. 

NOTE

This call has no effect on the processing of synchronous faults such as floating-point and overflow exceptions, access violations, and so on.
