.TH ZMODMUL 3 libzahl
.SH NAME
zmodmul - Calculate the modular product of two big integer
.SH SYNOPSIS
.nf
#include <zahl.h>
void zmodmul(z_t \fIproduct\fP, z_t \fImultiplier\fP, z_t \fImultiplicand\fP, z_t \fImodulator\fP);
.fi
.SH DESCRIPTION
.B zmodmul
calculates the product of a
.I multiplier
and a
.IR multiplicand ,
modulus a
.IR modulator ,
and stores the result in
.IR product .
That is,
.I product
gets
.RI ( multiplier
⋅
.IR multiplicand )
Mod
.IR modulator .
.P
It is safe to call
.B zmodmul
with non-unique parameters.
