System calls for cp and mv

Which system calls are made for operations cp and mv
# 2  
For cp :- read and write system calls
For mv :- Only the file name in the directory entry will be updated and the pointer to i-node for the file contents remains unchanged.
# 3  
Just a small correction. mv across filesystems will use read syscall to read the source file, write to write to the destination file and probably unlink to remove the file from the source directory. inode numbers may change in moves across filesystems.
