SYNOPSIS

subroutine process_close(fp,ierr)

      type(streampointer) :: fp
      integer             :: ierr

DESCRIPTION

The M_process Fortran procedures use the ISO_C_BINDING interface to define Fortran-callable versions of the C procedures popen(3c)/pclose(3c) and fgets(3c)/fputs(3c). A set of record-oriented wrapper routines are then used to create a simple Fortran-callable interface.
A POSIX C interface is generally available but may require using a Linux subwindow or an application such as CygWin on MSWindows platforms.
See "M_process" for an extended description.

OPTIONS

fp C file pointer returned by process_open_*()

ierr error flag returned.

EXAMPLES

This example shows a simple open and close of a process

program demo_process_close use M_process ,ONLY: process_open_read, process_open_write use M_process ,ONLY: streampointer, process_close implicit none type(streampointer) :: fp integer :: ierr ! open process to read from call process_open_read(’ls -l’,fp,ierr) write(*,*)’CLOSE : process is opened with status ’,ierr call process_close(fp,ierr) write(*,*)’CLOSE : process closed with status ’,ierr end program demo_process_close

Sample output:

CLOSE : process is opened with status 0 CLOSE : process closed with status 13
