Hi people

Recently i downloaded libsocket 0.7.4 beta 3 by R(?ichard 
)D(?avis)(forgor teh name:)). I discovered these bugs that
are in linux manpages also. 
1) DEMO program servern which should be in nonblocking mode
has wrong option set in fcntl(socket,SET_FL(or 
wahtever),O_NONBLOCK(!!!)). That's it.
ANother thing is that setsockopt(socket,SOL_SOCK,RCWLOVAT);
It should set minimum input buffer(the last define is prob. wrong)
(i don't have man pages right here)).In libsocket it writes(errno)
ENOPROTOSYS  - function not supported at this level.
That's a good joke!
Last thing that is even in linux man mage recv(2).
It's stated there that i can use recv(socket, buf, 
sizeof(buf),MSG_WAITALL) to get the whole buffer filled(blocking or 
not..)). Alas there is no such constant as MSG_WAITALL defined in all 
the linux includes. Friend of mine found MSG_WAITALL define(0x44) in 
some WURG or so sources but not in his linux. I don't really think 
that all this is flaw of libsocket. It's more probably flaw in linux 
functions.
