IPXFWEXITSTATUS
POSIX Function: Returns the exit code of a child process. This routine is only available for Linux.
Module
USE IFPOSIX
result = IPXFWEXITSTATUS (istat)
istat |
(Input) INTEGER(4). The value of output argument istat from PXFWAIT or PXFWAITPID. |
Results
The result type is INTEGER(4). The result is the low-order eight bits of the output argument of PXFWAIT or PXFWAITPID.
The IPXFWEXITSTATUS function should only be used if PXFWIFEXITED returns TRUE.
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
