This works exactly like vswprintf() but doesn't require access to a C runtime.
Defined in <SDL3/SDL_stdinc.h>
int SDL_vswprintf(wchar_t *text, size_t maxlen, const wchar_t *fmt, va_list ap);
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. |
(int) Returns the number of wide characters that should be written, not counting the null-terminator char, or a negative value on error.
Functions identically to SDL_swprintf(), except it takes a va_list
instead of using ...
variable arguments.
It is safe to call this function from any thread.
This function is available since SDL 3.2.0.
