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 explain_popen(3), and then the process terminates by calling exit(EXIT_FAILURE). This function is intended to be used in a fashion similar to the following example:

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 information. On failure, prints an explanation and exits.
