SDL_wcsnlen3
This works exactly like wcsnlen() but doesn't require access to a c runtime.
Usage
#include "SDL3/SDL.h"
size_t SDL_wcsnlen(const wchar_t *wstr, size_t maxlen);
Header file
Defined in SDL3/SDL_stdinc.h
Overview
Counts up to a maximum of maxlen wchar_t values in wstr , excluding the null terminator.
Like SDL_strnlen
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).
Also, maxlen is a count of wide characters, not bytes!
Function parameters
wstr
|
The null-terminated wide string to read. Must not be NULL. |
|---|---|
maxlen
|
The maximum amount of wide characters to count. |
Return value
Returns the length (in wide characters, excluding the null terminator) of wstr but never more than maxlen .
Thread safety
It is safe to call this function from any thread.
