PXFEXIT, PXFFASTEXIT

POSIX Subroutine: Exits from a process.

Module

USE IFPOSIX

CALL PXFEXIT (istatus)

CALL PXFFASTEXIT (istatus)

istatus

(Input) INTEGER(4). The exit value.

The PXFEXIT subroutine terminates the calling process. It calls, in last-in-first-out (LIFO) order, the functions registered by C runtime functions atexit and onexit, and flushes all file buffers before terminating the process. The istatus value is typically set to zero to indicate a normal exit and some other value to indicate an error.

The PXFFASTEXIT subroutine terminates the calling process without processing atexit or onexit, and without flushing stream buffers.

Example

program t1
use ifposix
integer(4) ipid, istat, ierror, ipid_ret, istat_ret
   print *," the child process will be born"
   call PXFFORK(IPID, IERROR)
   call PXFGETPID(IPID_RET,IERROR)
   if(IPID.EQ.0) then
     print *," I am a child process"
     print *," My child's pid is", IPID_RET
     call PXFGETPPID(IPID_RET,IERROR)
     print *," The pid of my parent is",IPID_RET
     print *," Now I have exited with code 0xABCD"
     call PXFEXIT(Z'ABCD')
   else
     print *," I am a parent process"
     print *," My parent pid is ", IPID_RET
     print *," I am creating the process with pid", IPID
     print *," Now I am waiting for the end of the child process"
     call PXFWAIT(ISTAT, IPID_RET, IERROR)
     print *," The child with pid ", IPID_RET," has exited"
     if( PXFWIFEXITED(ISTAT) ) then
       print *, " The child exited normally"
       istat_ret = IPXFWEXITSTATUS(ISTAT)
       print 10," The low byte of the child exit code is", istat_ret
     end if
   end if
10 FORMAT (A,Z)
end program
