NAME

CopyMemQuick - optimized memory copy function

SYNOPSIS

    CopyMemQuick( source, dest, size )
                  A0      A1    D0

    void CopyMemQuick(ULONG *,ULONG *,ULONG);

FUNCTION

CopyMemQuick is a highly optimized memory copy function, with restrictions on the size and alignment of its arguments. Both the source and destination pointers must be longword aligned. In addition, the size must be an integral number of longwords (e.g. the size must be evenly divisible by four).

Arbitrary overlapping copies are not supported.

The internal implementation of this function will change from system to system, and may be implemented via hardware DMA.

INPUTS

source - a pointer to the source data region, long aligned dest - a pointer to the destination data region, long aligned size - the size (in bytes) of the memory area. Zero copies zero bytes.
