Required Configuration
None.
Notes / Warnings
- Zero-sized copies allowed.
- Memory buffers not checked for overlapping. However, data octets from a source memory buffer at a higher address value should successfully copy to a destination memory buffer at a lower address value even if any octets of the memory buffers overlap as long as no individual copy overlaps. Since
Mem_Copy()
performs the data octet copy viaCPU_ALIGN
-sized words and/or octets; and sinceCPU_ALIGN
-sized words must be accessed on word-aligned addresses, neitherCPU_ALIGN
-sized words nor octets at unique addresses can ever overlap. Therefore,Mem_Copy()
should be able to successfully copy overlapping memory buffers as long as the source memory buffer is at a higher address value than the destination memory buffer. - This function can be configured to build an assembly-optimized version
