explain_freopen_or_die - open file and report errors
void explain_freopen_or_die(const char *pathname, const char *flags,
The explain_freopen_or_die function is used to reopen a file via the
freopen(3) system call. On failure it will print an explanation,
obtained from the 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
explain_freopen_or_die(pathname, flags, fp);
The pathname, exactly as to be passed to the freopen(3) system
flags The flags, exactly as to be passed to the freopen(3) system
fp The fp, exactly as to be passed to the freopen(3) system call.
Only ever return on success. Never returns on failure.
