# explain\_link\_or\_die(3)

make a new name for a file and report errors

## NAME

explain\_link\_or\_die - make a new name for a file and report errors

## SYNOPSIS

\#include \<libexplain/link.h\>

void explain\_link\_or\_die(const char \*oldpath, const char \*newpath);

## DESCRIPTION

The **explain\_link\_or\_die** function is used to call the [*link*(2)](/link/2.md) system call.  On failure an explanation will be printed to *stderr*, obtained from [*explain\_link*(3)](/explain_link/3.md), and then the process terminates by calling `exit(EXIT_FAILURE)`.

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

```
explain_link_or_die(oldpath, newpath);
```

- *oldpath*

  The oldpath, exactly as to be passed to the [*link*(2)](/link/2.md) system call.

- *newpath*

  The newpath, exactly as to be passed to the [*link*(2)](/link/2.md) system call.

- Returns:

  This function only returns on success. On failure, prints an explanation and exits.

- [*explain\_link*(3)](/explain_link/3.md)
