Function Documentation

int printf	(	const char *	fmt,
			...
	)

Definition at line 323 of file stdio.c.

int sprintf	(	char *	buf,
		const char *	fmt,
			...

int int vsprintf	(	char *	buf,
		const char *	fmt,
		va_list	args
	)

vsprintf - Format a string and place it in a buffer : The buffer to place the result into : The format string to use : Arguments for the format string

The function returns the number of characters written into . Use vsnprintf() or vscnprintf() in order to avoid buffer overflows.

If you're not already dealing with a va_list consider using sprintf().

See the vsnprintf() documentation for format string extensions over C99.
