SDL_vswprintf

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

Header File

Defined in <SDL3/SDL_stdinc.h>

Syntax

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

Function Parameters

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

Return Value

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

Remarks

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

Thread Safety

It is safe to call this function from any thread.

Version

This function is available since SDL 3.2.0.
