      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.
