Linux sockets - read\write() vs send\recv()?

Question

Hi all,

Just wondering if there's any good Linux sockets programmers who can tell me the difference between using Linux send() and recv() compared to read() and write() when using sockets? So far I've been using send() recv(), but very hard to get used to when recv() is supposed to return!

Answer 1

extracted from http://www.faqs.org/faqs/unix-faq/socket/ - has some very good information on sockets - i may be able to answer some more specific questions



From Andrew Gierth ([e-mail]):



read() is equivalent to recv() with a flags parameter of 0. Other

values for the flags parameter change the behaviour of recv().

Similarly, write() is equivalent to send() with flags == 0.



It is unlikely that send()/recv() would be dropped; perhaps someone

with a copy of the POSIX drafts for socket calls can check...



Portability note: non-unix systems may not allow read()/write() on

sockets, but recv()/send() are usually ok. This is true on Windows and

OS/2, for example.

i take advantage of a Mac and that i think of that's great. Key issues to observe concerning to the Mac: that's a steep gaining knowledge of curve coming from a homestead windows based gadget. that's in basic terms a sprint greater high priced than your homestead windows gadget.
