I wish to copy content of specific length from one buffer to another from a specific starting point. I checked memcpy() but it takes only the length of content to be copied while I want to specify the starting index too.

Is there any function which can do this or is there any good approach to do it with the existing memcpy function?

I always prefer the syntax 

memcpy( &dst[dstIdx], &src[srcIdx], numElementsToCopy * sizeof( Element ) );
