SDL_wcslen - Man Page
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.
