fctprintf()

int fctprintf	(	void(*)(char character, void *arg)	out,

printf with output function You may use this as dynamic alternative to printf() with its fixed _putchar() output

Parameters

out	An output function which takes one character and an argument pointer
arg	An argument pointer for user data passed to output function
format	A string that specifies the format of the output

Returns

The number of characters that are sent to the output function, not counting the terminating null character
