allows application to commit suicide

Part of [wnasrt(3)](/wnasrt/3.md).

## NAME

wn\_assert, wn\_assert\_notreached, wn\_assert\_warn, wn\_assert\_warn\_notreached, wn\_set\_assert\_print - allows application to commit suicide

## SYNOPSIS

```
#include <wn/wnasrt.h>

wn_assert(bool condition)

wn_assert_notreached()

wn_assert_warn(bool condition)

wn_assert_warn_notreached()

wn_set_assert_print(passert_print)
void (*passert_print)(/*string*/); /* char string[]; */
```

## DESCRIPTION

**wn\_assert** evaluates *condition*.  If *condition* is **TRUE**, execution continues.  If *condition* is **FALSE**, it  prints a message giving the file name and line number where it was called from.  Then it crashes the application using [abort(3)](/abort/3.md).

**wn\_assert\_notreached** prints a message giving the file name and  line number where it was called from.  Then it crashes the application using [abort(3)](/abort/3.md).

**wn\_assert\_warn** evaluates *condition*.   If *condition* is FALSE, it  prints a message giving the file name and line number where it was called from.

**wn\_assert\_warn\_notreached** prints a message giving the file name and  line number where it was called from.

**wn\_set\_assert\_print** allows the programmer to change the routine used for printing messages.  The default is to print to standard error.
