SDL_wcslen - Man Page

#include <SDL3/SDL_stdinc.h>

size_t SDL_wcslen(const wchar_t *wstr);

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).

wstr

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

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

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
