posix.MSG definition for macos is missing

[dacheng-gao]

I don't know if is correct to convert from /Library/Developer/CommandLineTools/SDKs/MacOSX15.5.sdk/usr/include/sys/socket.h.

see https://github.com/apple/darwin-xnu/blob/main/bsd/sys/socket.h#L991
see also https://github.com/apple-oss-distributions/xnu/blob/main/bsd/sys/socket.h#L642

pub const MSG = struct {
 /// process out-of-band data
 pub const OOB = 0x1;
 /// peek at incoming message
 pub const PEEK = 0x2;
 /// send without using routing tables
 pub const DONTROUTE = 0x4;
 /// data completes record
 pub const EOR = 0x8;
 /// data discarded before delivery
 pub const TRUNC = 0x10;
 /// control data lost before delivery
 pub const CTRUNC = 0x20;
 /// wait for full request or error
 pub const WAITALL = 0x40;
 /// this message should be nonblocking
 pub const DONTWAIT = 0x80;
 /// data completes connection
 pub const EOF = 0x100;
 /// wait up to full request, may return partial
 pub const WAITSTREAM = 0x200;
 /// Start of 'hold' seq; dump so_temp, deprecated
 pub const FLUSH = 0x400;
 /// Hold frag in so_temp, deprecated
 pub const HOLD = 0x800;
 /// Send the packet in so_temp, deprecated
 pub const SEND = 0x1000;
 /// Data ready to be read
 pub const HAVEMORE = 0x2000;
 /// Data remains in current pkt
 pub const RCVMORE = 0x4000;
 /// Fail receive if socket address cannot be allocated
 pub const NEEDSA = 0x10000;
 /// do not generate SIGPIPE on EOF
 pub const NOSIGNAL = 0x80000;
 /// Inherit upcall in sock_accept
 pub const USEUPCALL = 0x80000000;
};

Sounds fine.

By the way, where is the best place to place this, extend MSG in c.zig or put it into os/darwin.zig?

[alexrp]

Probably the latter.
