NAME

       SDL_wcsnlen - This works exactly like wcsnlen() 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_wcsnlen(const wchar_t *wstr, size_t maxlen);

DESCRIPTION

       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.

AVAILABILITY

       This function is available since SDL 3.2.0.
