NAME

PXFGETPGRP - Gets the process group ID

SYNOPSIS

INTEGER ipgrp, ierror
CALL PXFGETPGRP(ipgrp, ierror)

IMPLEMENTATION

Cray Linux Environment (CLE)

STANDARDS

IEEE 1003.9-1992 standard interface for FORTRAN 77

DESCRIPTION

The PXFGETPGRP subroutine uses the getpgrp(2) system call to return the process group ID of the calling process.

All arguments must be of default kind unless documented otherwise. Default kind is KIND=4 for integer, real, complex, and logical arguments.

The following is a list of valid arguments for this routine:

ipgrp: An output integer variable that contain the process group ID for the current process.
ierror: An output integer variable that contains a status of zero if the process ID was successfully acquired.

EXAMPLES

In this example, PXFGETPGRP will return the process group ID for the calling process.

program pxftest
integer ipgrp, ierror

CALL PXFGETPGRP(ipgrp, ierror)
if (ierror .eq. 0) then
    print *,'pgrp = ',ipgrp
else
    print *,'error = ', ierror
endif
end
