Function Documentation

xformat()

unsigned xformat	(	void(*)(void *arg, char)	outchar,
		void *	arg,
		const char *	fmt,
			...
	)

Formats and outputs a string according to a format string 'fmt' and an arbitrary number of variable arguments.

The output is written character by character using a user-defined output function 'outchar'.

Parameters

outchar	The output function that writes a single character.
arg	A pointer to optional arguments for the output function.
fmt	The format string specifying the output format.
...	The variable arguments containing the values to be formatted and output.

Returns

The number of characters written.

xvformat()

unsigned xvformat	(	void(*)(void *arg, char)	outchar,
		void *	arg,
		const char *	fmt,
		va_list	args
	)

Formats and outputs a string according to a format string 'fmt' and a variable argument list 'args'.

The output is written character by character using a user-defined output function 'outchar'.

Parameters

outchar	The output function that writes a single character.
arg	A pointer to optional arguments for the output function.
fmt	The format string specifying the output format.
args	The variable argument list containing the values to be formatted and output.

Returns

The number of characters written.
