NAME

SDL_vsnprintf - This works exactly like vsnprintf() but doesn’t require access to a C runtime.

HEADER FILE

Defined in SDL3/SDL_stdinc.h

SYNOPSIS

#include "SDL3/SDL.h"

int SDL_vsnprintf(char *text, size_t maxlen, const char *fmt, va_list ap);

DESCRIPTION

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

FUNCTION PARAMETERS

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

RETURN VALUE

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

THREAD SAFETY

It is safe to call this function from any thread.

AVAILABILITY

This function is available since SDL 3.2.0.
