NAME

SDL_wcsnstr - Search a wide string, up to n wide chars, for the first instance of a specific substring.

Defined in SDL3/SDL_stdinc.h

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.

FUNCTION PARAMETERS

haystack

	needle		the wide string to search for. Must not be NULL.
	maxlen		the maximum number of wide characters to search in haystack .

RETURN VALUE

Returns a pointer to the first instance of needle in the string, or NULL if not found.

THREAD SAFETY

It is safe to call this function from any thread.

AVAILABILITY

This function is available since SDL 3.2.0.
