	1 .TH ZNOT 3 libzahl
	2 .SH NAME
	3 znot - Calculate the bitwise complement of a big integer
	4 .SH SYNOPSIS
	5 .nf
	6 #include <zahl.h>
	7
	8 void znot(z_t \fIa\fP, z_t \fIb\fP);
	9 .fi
	10 .SH DESCRIPTION
	11 .B znot
	12 calculates the bitwise complement of
	13 .I b
	14 and stores the result in
	15 .IR a .
	16 .P
	17 It is safe to call
	18 .B znot
	19 with
	20 .IR "(a==b)" .
	21 .SH NOTES
	22 Be aware, the following code will halt for any input
	23 .P
	24 .nf
	25 #include <zahl.h>
	26
	27 void
	28 silly(z_t a)
	29 {
	30 while (!zzero(a))
	31 znot(a, a);
	32 }
	33 .fi
	34 .P
	35 Also note that
	36 .B z_t
	37 uses neither two's complement, ones' complement, nor
	38 sign-and-magnitude.
