Subject: Evas events: fix for works with pipes on windows.
X-Git-Tag: accepted/tizen/common/20170102.152350~222
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bfbff7c411cba997c234d1600b91bfb77d70d489;p=platform%2Fupstream%2Fefl.git

Evas events: fix for works with pipes on windows.

Evil implementation of pipe() function uses sockets. Windows functions
"write", "read" and "close" doesn't works with sockets. In this commit
added macros, that replace "read" with "recv", "write" with "send" and
"close" with "closesocket".

@fix
