SDL_strnlen - This works exactly like strnlen() but doesn't require access to a C runtime.

       This function is available since SDL 3.2.0.

       Counts up to a maximum of maxlen bytes in str , excluding the null terminator.

       If you need the length of a UTF-8 string, consider using

       SDL_utf8strnlen ().

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

       maxlen The maximum amount of bytes to count.

       Defined in SDL3/SDL_stdinc.h

       SDL_strnlen - This works exactly like strnlen() but doesn't require access to a C runtime.
