# SDL\_strcmp(3)

Compare two null-terminated UTF-8 strings.

## NAME

SDL\_strcmp - Compare two null-terminated UTF-8 strings.

## HEADER FILE

Defined in SDL3/SDL\_stdinc.h

## SYNOPSIS

```
#include "SDL3/SDL.h"
```

**int SDL\_strcmp(const char \*str1, const char \*str2);**

## DESCRIPTION

Due to the nature of UTF-8 encoding, this will work with Unicode strings, since effectively this function just compares bytes until it hits a null-terminating character. Also due to the nature of UTF-8, this can be used with  **SDL\_qsort** () to put strings in (roughly) alphabetical order.

## FUNCTION PARAMETERS

- *str1*

  the first string to compare. NULL is not permitted!

- *str2*

  the second string to compare. NULL is not permitted!

## RETURN VALUE

Returns less than zero if str1 is "less than" str2, greater than zero if str1 is "greater than" str2, and zero if the strings match exactly.

## THREAD SAFETY

It is safe to call this function from any thread.

## AVAILABILITY

This function is available since SDL 3.2.0.
