# explain\_freopen\_or\_die(3)

open file and report errors

## NAME

explain\_freopen\_or\_die - open file and report errors

## 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 [*freopen*(3)](/freopen/3.md) 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)](/freopen/3.md) system call.

- *flags*

  The flags, exactly as to be passed to the [*freopen*(3)](/freopen/3.md) system call.

- *fp*

  The fp, exactly as to be passed to the [*freopen*(3)](/freopen/3.md) system call.

- Returns:

  Only ever return on success. Never returns on failure.
