NAME
- CopyMem
-
general purpose memory copy function
SYNOPSIS
CopyMem( source, dest, size )
void CopyMem(APTR,APTR,ULONG);
A0 A1 D0
FUNCTION
CopyMem is a general purpose, fast memory copy function. It can deal with arbitrary lengths, with its pointers on arbitrary alignments. It attempts to optimize larger copies with more efficient copies, it uses byte copies for small moves, parts of larger copies, or the entire copy if the source and destination are misaligned with respect to each other.
The internal implementation of this function will change from system to system, and may be implemented via hardware DMA.
CAUTION
The internal implementation of this function will change from system to system, and may be implemented via hardware DMA.
CAUTION
Arbitrary overlapping copies are not supported.
INPUTS
- source
-
a pointer to the source data region
- dest
-
a pointer to the destination data region
- size
-
the size (in bytes) of the memory area. Zero copies zero bytes
