A Python interface to sendfile(2) syscall.
|
|
|
|
sendfile(2) is a system call which provides a "zero-copy" way of
|
|
copying data from one file descriptor to another (a socket).
|
|
|
|
The phrase "zero-copy" refers to the fact that all of the copying of
|
|
data between the two descriptors is done entirely by the kernel, with
|
|
no copying of data into userspace buffers. This is particularly useful
|
|
when sending a file over a socket (e.g. FTP).
