SYNOPSIS

#include <libexplain/freopen.h>
void explain_freopen_or_die(const char *pathname, const char *flags, FILE *fp);

DESCRIPTION

The explain_freopen_or_die function is used to reopen a file via the I]freopen(3) system call. On failure it will print an explanation, obtained from the I]linexplain_freopen(3) function, on the standard error stream and then exit.

This function is intended to be used in a fashion similar to the following example:

explain_freopen_or_die(pathname, flags, fp);

I]pathname
  The pathname, exactly as to be passed to the I]freopen(3) system call.
I]flags The flags, exactly as to be passed to the I]freopen(3) system call.
I]fp The fp, exactly as to be passed to the I]freopen(3) system call.
Returns: Only ever return on success. Never returns on failure.
