# PXFPAUSE

POSIX Subroutine: Suspends process execution.

## Module

USE IFPOSIX

CALL PXFPAUSE (ierror)

ierror | (Output) INTEGER(4). The error status.

The PXFPAUSE subroutine causes the invoking process (or thread) to sleep until a signal is received that either terminates it or causes it to call a signal-catching function.
