Peeking at data on a socket (MSG_PEEK?)

Hi networkers,

I am hoping to be able to peek at data on a socket I have connected in my application, so I look at the start of the data, and still let existing functions read the entire data later. Much like this guy actually: <http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&oe=UTF- 8&threadm=email@hidden&rnum=2&prev=/ groups?q=peek+socket&hl=en&lr=&ie=UTF-8&oe=UTF- 8&selm=3B55A87B.1030606%40uk.ibm.com&rnum=2>

To that end, I've found the MSG_PEEK option to the recv call, which looks perfect, is documented in man recv and appears in the header. I'm wondering if this option is supported on Mac OS X and if there are any pointers on its use. In particular, I imagine you can't loop around filling your peek data, like you normally do to get all the data out of the socket, so it is a one off shot and the data. Any other catches?

Cheers,
Heath
