NAME
- CopyMemQuick
-
optimized memory copy function
SYNOPSIS
CopyMemQuick( source, dest, size )
void CopyMemQuick(ULONG *,ULONG *,ULONG);
A0 A1 D0
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).
The internal implementation of this function will change from system to system, and may be implemented via hardware DMA.

WARNING
Arbitrary overlapping copies are not supported.
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.
