Chapter 26. Sockets

void *optval, socklen_t *optlen);

int (*setsockopt)( cyg_file *fp, int level, int optname,

const void *optval, socklen_t optlen);

int (*sendmsg)

( cyg_file *fp, const struct msghdr *m,

int flags, ssize_t *retsize );

int (*recvmsg)

( cyg_file *fp, struct msghdr *m,

socklen_t *namelen, ssize_t *retsize );

};

It should be obvious from the names of these functions which API calls they provide support for. The

get-

name()

function pointer provides support for both

getsockname()

and

getpeername()

while the

sendmsg()

and

recvmsg()

function pointers provide support for

send()

sendto()

sendmsg()

recv()

recvfrom()

and

recvmsg()

as appropriate.
