.SH NAME
\fBicpy\fP \- copying the value of an integer variable
.SH SYNOPSIS
.nf
.B #include <libmpu.h>
.PP
.BI "void icpy( mpu_int *" c ", mpu_int *" a ", int " nb_c ", int " nb_a " );
.fi
.SH DESCRIPTION
The \fBicpy()\fP function performs the operation of copying the value of the \fBa\fP operand
to the variable, located at the address \fBc\fP. The contents of the memory at address \fBa\fP
are not changed, and the previous memory at address \fBc\fP is lost. The \fBnb_c\fP parameter
determines the size of the operand (in bytes) located at address \fBc\fP, and the \fBnb_a\fP
parameter determines the size of the operand (in bytes) located at the address \fBa\fP.
.PP
The function affects the flags \fBO\fP, \fBP\fP, \fBS\fP, \fBZ\fP.
.PP
The flags \fBA\fP, \fBC\fP do not change (the previous value is retained).
The \fBP\fP flag is set only when the size of the \fBc\fP operand is one
or two bytes (\fBnb\fP == 1 || \fBnb\fP == 2).
