NAME
     pfm_$inhibit - inhibit asynchronous faults

SYNOPSIS (C)
     #include <apollo/base.h>
     #include <apollo/pfm.h>

     void pfm_$inhibit(void);

SYNOPSIS (Pascal)
     %include '/sys/ins/base.ins.pas';
     %include '/sys/ins/pfm.ins.pas';

     procedure pfm_$inhibit;

SYNOPSIS (FORTRAN)
     %include '/sys/ins/base.ins.ftn'
     %include '/sys/ins/pfm.ins.ftn'

           call pfm_$inhibit

DESCRIPTION
     Pfm_$inhibit prevents asynchronous faults from being passed to the cal-
     ling process.  While faults are inhibited, the operating system holds at
     most one asynchronous fault.  Consequently, a call to pfm_$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.

NOTES
     Pfm_$inhibit has no effect on the processing of synchronous faults such
     as floating-point and overflow exceptions, access violations, and so on.
