memcpy w/ an offset?

memcpy w/ an offset?

If I have a buffer of 4 doubles that i just read from a socket, how do I copy the 3rd double into a value by itself? There's no delimiters, just serialized data that I read in.

Is there something like a memcpy w/ an offset somehow?

RE: memcpy w/ an offset?

What's the datatype of the buffer?
If it's something like a char* buffer, you should be able to just cast it:


char* buf;
double value = ((double*)buf)[2];
double value = *(((double*)buf) + 2);
