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