+
+ NetLib :
+
+ Instead of you writing all the code for working with sockets and supporting
+ app level protocols such as SOCKS5, it's all done for you.
+
+ NetLib takes care of all that and you can even register a special abstract
+ nexus, e.g. ICQ direct, the user can configure all this from the options dialog
+ and you don't have to bother with any of it.
+
+ NetLib wraps up any Winsock calls but you can still get the socket handle
+ from your netlib handle and do stuff.
+
+ It gives all modules an abstract way of dealing with transport -- mainly sockets
+ and proxies, Now the but..
+
+ It's new (mmmm) thus unsupported by any older version of Miranda, and if you
+ want to be lazy and not write any "wrapper" mini netlib then you'll have
+ the kudos of "only works with nightly build version of Miranda" :)

+ This service uses some of the same flags as MS_NETLIB_SEND :
+ MSG_PEEK,
+ MSG_NODUMP,
+ MSG_DUMPPROXY,
+ MSG_NOHTTPGATEWAYWRAP,
+ MSG_DUMPASTEXT,
+ MSG_RAW
+ -
+ On using MSG_NOHTTPGATEWAYWRAP: Because packets through an HTTP proxy are
+ batched and cached and stuff, using this flag is not a guarantee that it
+ will be obeyed, and if it is it may even be propogated to future calls
+ even if you don't specify it then. Because of this, the flag should be
+ considered an all-or-nothing thing: either use it for the entire duration
+ of a connection, or not at all.
+ Errors : ERROR_INVALID_PARAMETER, anything from recv()
+ (HTTP proxy):
+ ERROR_GEN_FAILURE (http result code wasn't 2xx)
+ ERROR_INVALID_DATA (no Content-Length header in reply)
+ ERROR_NOT_ENOUGH_MEMORY (Content-Length very large)
+ ERROR_HANDLE_EOF (connection closed before Content-Length bytes recved)
+ anything from select(),
+ MS_NETLIB_RECVHTTPHEADERS, nlu.pfnHttpGatewayUnwrapRecv, socket(),

+ Notes : The packet receiver implements the common situation where
+ you have a variable length of packets coming thru over a connection
+ and you want them split up in order to handle them.
+ -
+ The major limiation is, that the buffer is created in memory,

+ Returns: The total number of bytes available in the buffer, NULL(0)
+ if the connection was closed or SOCKET_ERROR.
+ -
+ If TNETLIBPACKETRECVER.bytesUsed is set to zero and the
+ buffer is already full up to the maxPacketSize, it is assumed
+ that a too large packet has been received, All data in
+ the buffer is discarded and receiving has started anew.
+ -
+ This will probably cause alignment problem so if you think
+ that tis iss likely to happen, then you should deal with it
+ yourself.
+ -
+ Closing the packet receiver will not close the associated
+ connection but will discard any bytes still in the buffer,
+ so if you intend to carry on reading from that connection,
+ make sure you have processed the buffer first.
+ -
+ This service is equivalent of memmove() to remove
+ the first bytesUsed from the buffer, select(), if dwTimeOut
