Does vaprintf support %s??

When I use vaprintf in a text print function that has the multiple argument thing, and I use %s in the input text, with it's respective char string, it doesn't work(the print function doesn't display it). I have had this problem before, but now I actually care. So does vaprintf support %s or do I have to use something else? Thanks alot!

Code:

Print(GLint x, GLint y, const char *string, ...)	// Where The Printing Happens
{    
char		text[256];
	va_list		ap;										// Pointer To List Of Arguments

	if (string == NULL)									// If There's No Text
		return;											// Do Nothing

	va_start(ap, string);									// Parses The String For Variables
	    vsprintf(text, string, ap);						// And Converts Symbols To Actual Numbers
	va_end(ap);	

//There's more to this I just edited it out
}

//And I call it like:

Print(100,100, "console: %s", console[CurrentLine].string);

Yes it does

> Print(100,100, "console: %s", console[CurrentLine].string);
Does
- console[CurrentLine].string have a \0
- is the combined result < 256 chars

Perhaps

char text[256];

Should be bigger for your use
