c - Does SO_RCVTIMEO affect accept()? -

-

does so_rcvtimeo option affect accept (causing return eagain or ewouldblock if timeout expires)? there behavior specified standard? can't find in documentation accept or use of options:

http://pubs.opengroup.org/onlinepubs/9699919799/functions/v2_chap02.html#tag_15_10_16

while on posix so_rcvtimeo defined "an input function", , so_sndtimeo defined "an output function", can'r find definition "input function" or "output function", i'll read/receive , write/send @ least.

in specific case of linux, so_rcvtimeo affects accept(), can seen looking @ inet_csk_accept(), , so_snd_timeo affects connect(), can seen looking @ tcp_sendmsg().
