explain_freopen_or_die3
Open file and report errors
Usage
#include <libexplain/freopen.h>
void explain_freopen_or_die(const char *pathname, const char *flags, FILE *fp);
Overview
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 following example:
explain_freopen_or_die(pathname, flags, fp);
pathname
|
The pathname, exactly as to be passed to the freopen(3) system call. |
|---|---|
flags
|
The flags, exactly as to be passed to the freopen(3) system call. |
fp
|
The fp, exactly as to be passed to the freopen(3) system call. |
Returns:
|
Only ever return on success. Never returns on failure. |
