Synopsis

#include <libexplain/fdopen.h>

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

Description

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.
