pfm_$inhibit (void)
The pfm_$inhibit 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 the pfm_$inhibit routine can result in the loss of some signals. For that and other reasons, it is good practice to inhibit faults only when absolutely necessary.
To prevent asynchronous interrupts from occurring in a critical portion of a routine, use the following:
pfm_$inhibit( );
