| |
Hi, All
We were looking at "[kernel]/lib/string.c" (http://lxr.linux.no/source/lib/string.c#L500)
memcpy copies a part of memory to some other location but It will not work for all cases of overlapping blocks.(if the start of destination block falls between the source block)
while memove copes with overlapping areas.
then why is memcpy present in the sources can't we simply do
"#define memcpy memmove" in include/linux/string.h
or am I missing something?
Regards Sri
