NAME

SDL_wcslen - This works exactly like wcslen() but doesn’t require access to a C runtime.

HEADER FILE

Defined in SDL3/SDL_stdinc.h

SYNOPSIS

#include "SDL3/SDL.h"

size_t SDL_wcslen(const wchar_t *wstr);

DESCRIPTION

Counts the number of wchar_t values in wstr , excluding the null terminator.

Like SDL_strlen
only counts bytes and not codepoints in a UTF-8 string, this counts wchar_t values in a string, even if the string’s encoding is of variable width, like UTF-16.

Also be aware that wchar_t is different sizes on different platforms (4 bytes on Linux, 2 on Windows, etc).

FUNCTION PARAMETERS

wstr

The null-terminated wide string to read. Must not be NULL.

RETURN VALUE

Returns the length (in wchar_t values, excluding the null terminator) of wstr .

THREAD SAFETY

It is safe to call this function from any thread.

AVAILABILITY

This function is available since SDL 3.2.0.
