explain_popen_or_die(3)     Library Functions Manual	 explain_popen_or_die(3)

NAME
     explain_popen_or_die - process I/O and report errors

SYNOPSIS
     #include <libexplain/popen.h>
     FILE *explain_popen_or_die(const char *command, const char *flags);

DESCRIPTION
     The explain_popen_or_die function is used to call the popen(3) system call.
     On  failure  an  explanation  will  be printed to stderr, obtained from ex-
     plain_popen(3), and then the process terminates by calling  exit(EXIT_FAIL-
     URE).

     This  function is intended to be used in a fashion similar to the following
     example:
	    FILE *fp = explain_popen_or_die(command, flags);

     command
	     The command, exactly as to be passed to the popen(3) system call.

     flags   The flags, exactly as to be passed to the popen(3) system call.

     Returns:
	     This function only returns on success, see popen(3) for more infor-
	     mation.  On failure, prints an explanation and exits.
