.SH NAME
Quad_AddUns, Quad_AddUnsLong \- Arithmetic operations on 64-bit integers
.SH SYNOPSIS
.nf
\fB#include <quad.h>\fR
.sp
void
\fBQuad_AddUns\fR(\fIuQuad1\fR, \fIuQuad2\fR, \fIuResultPtr\fR)
.sp
void
\fBQuad_AddUnsLong\fR(\fIuQuad1\fR, \fIuLong\fR, \fIuResultPtr\fR)
.SH ARGUMENTS
.AS u_quad *uResultPtr
.AP u_quad uQuadN in
N'th unsigned quad operand
.AP u_long uLong in
unsigned long operand
.AP u_quad *uResultPtr out
unsigned quad result
.BE
.SH DESCRIPTION
.PP
Sprite provides some common operations on 64-bit integers.
.B Quad_AddUns
adds two unsigned quads together.
.B Quad_AddUnsLong
adds an unsigned long to an unsigned quad. In both cases, one of the
quad operands can also be used to hold the result.
.PP
It is expected that more quad operations will be added to the library
as they are needed for different applications.
.SH KEYWORDS
quad, arithmetic, counter
