SDL_vswprintf - Man Page

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

Header File

Defined in SDL3/SDL_stdinc.h

#include "SDL3/SDL.h"

int SDL_vswprintf(wchar_t *text, size_t maxlen, const wchar_t *fmt, va_list ap);

Functions identically to SDL_swprintf (), except it takes a va_list instead of using ... variable arguments.

text: the buffer to write the string into. Must not be NULL.
maxlen: the maximum wide characters to write, including the null-terminator.
fmt: a printf-style format wide string. Must not be NULL.
ap: a va_list values to be used with the format string.

Returns the number of wide characters that should be written, not counting the null-terminator char, or a negative value on error.

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
