NAME

       rfio_popen, rfio_pclose - start a process and open a pipe to it

SYNOPSIS

       #include <sys/types.h>
       #include "rfio_api.h"

       FILE *rfio_popen (const char *command, const char *type);

       int rfio_pclose (FILE *fs);

DESCRIPTION

       rfio_popen starts a process and opens a pipe to it.

       command is a pointer to a string specifying the shell command to be executed.

       type is a mode indicator for the pipe. One of the characters "r" or "w".

       rfio_pclose  waits  for the forked process to terminate and returns the exit status of the
       command.

EXAMPLE

            int c;
            FILE *rf;

            rf = rfio_popen (command, "r");
            if (rf == NULL) {
                 rfio_perror ("rfio_popen");
                 exit (1);
            }
            while ((c = rfio_pread (buf, 1, sizeof(buf), rf)) > 0) {
                 ...
            }
            c = rfio_pclose (rf);

RETURN VALUE

       This routine returns NULL if the  operation  failed  or  a  non-NULL  pointer  to  a  FILE
       structure  if  the  operation  was  successful.  If  it  fails,  serrno  variable  is  set
       appropriately.
