[MPlayer-dev-eng] question about posix select

[Mate Miklos]

Hi,

can anyone tell me what is the reason for the HAVE_NO_POSIX_SELECT macro 
controlled by configure? Which OS's don't have posix select?

This macro is only used in input/input.c and libmpcodecs/vf_bmovl.c, but the 
select() call is used in various other places as well, eg. stream/tcp.c, 
stream/stream_ftp.c.

What's more interesting, input.c:mp_input_read_key_code() calls getch2() which 
uses select() again, but without the guarding macro.

The getch2.c file has an alternative, getch2-win.c, so I guess windoze doesn't 
have select(), but then how does the above two streams compile on windoze?

Or, if a Unix-like OS doesn't have select() (which is highly unlikely...), 
then the following audio out drivers shouldn't compile because of select() 
usage: ao_oss, ao_sun, ao_esd

(and libavformat also uses select() in rtpproto.c, tcp.c, audio.c and 
rtsp.c ...)

Personally I use Linux, so I'm not affected by this, I'm just curious...
