NAME

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

SYNOPSIS

#include <SDL3/SDL_stdinc.h>

int SDL_vasprintf(char **strp, const char *fmt, va_list ap);

DESCRIPTION

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

FUNCTION PARAMETERS

strp

on output, is set to the new string. Must not be NULL.

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 in the newly-allocated string, 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.
