SYNOPSIS

#include "SDL3/SDL.h"

wchar_t * SDL_wcsnstr(const wchar_t *haystack, const wchar_t *needle, size_t maxlen);

DESCRIPTION

The search ends once it finds the requested substring, or a null terminator value to end the string, or maxlen wide character have been examined. It is possible to use this function on a wide string without a null terminator.

Note that this looks for strings of _wide characters_, not _codepoints_, so it's legal to search for malformed and incomplete UTF-16 sequences.
