◆ ABS

#define ABS ( a ) ((a)<0?-(a):(a))

Definition at line 109 of file rpng2-win.c.

		fg,
		alpha,
		bg
	)

Value:

#define INBUFSIZE

Value:

4096   /* with pseudo-timing on (1 sec delay/block), this

                          *  speed 10% faster than theoretical 33.6K maximum
                          *  (assuming 8 data bits, 1 stop bit and no other
                          *  overhead) */
