explain_fdopen_or_die - stream open functions and report errors

SYNOPSIS

#include <libexplain/fdopen.h>

void explain_fdopen_or_die(int fd, const char *mode);

DESCRIPTION

The explain_fdopen_or_die function is used to call the fdopen(3) system call. On failure an explanation will be printed to stderr, obtained from explain_fdopen(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:

FILE *fp = explain_fdopen_or_die(fd, mode);

fd

The fd, exactly as to be passed to the fdopen(3) system call.

mode

The mode, exactly as to be passed to the fdopen(3) system call.

Returns:

This function only returns on success. On failure, prints an explanation and exits.
