NAME
suffix_detach - terminates SUFFIX protocol and returns the underlying socketSYNOPSIS
-
#include <libdill.h> int suffix_detach( int s, int64_t deadline);
DESCRIPTION
SUFFIX is a message-based protocol that delimits messages by specific byte sequences. For example, many protocols are line-based, with individual messages separated by CR+LF sequence.This function does the terminal handshake and returns underlying socket to the user. The socket is closed even in the case of error.
s: Handle of the SUFFIX socket.
deadline: A point in time when the operation should time out, in milliseconds. Use the now function to get your current point in time. 0 means immediate timeout, i.e., perform the operation if possible or return without blocking if not. -1 means no deadline, i.e., the call will block forever if the operation cannot be performed.
This function is not available if libdill is compiled with --disable-sockets option.
RETURN VALUE
In case of success the function returns underlying socket handle. In case of error it returns -1 and sets errno to one of the values below.ERRORS
- •
- EBADF: Invalid handle.
- •
- ECANCELED: Current coroutine was canceled.
- •
- ECONNRESET: Broken connection.
- •
- ENOTSUP: The handle is not a SUFFIX protocol handle.
- •
- ETIMEDOUT: Deadline was reached.
EXAMPLE
-
int s = tcp_connect(&addr, -1); s = suffix_attach(s, " ", 2); msend(s, "ABC", 3, -1); char buf[256]; ssize_t sz = mrecv(s, buf, sizeof(buf), -1); s = suffix_detach(s, -1); tcp_close(s);
