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);

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.
