mongoc_socket_sendv: Sends a vector of buffers to the destination. This uses sendmsg() when available to perform a gathered write. If IOV_MAX is reached, a fallback will be used.

NAME

mongoc_socket_sendv() - Sends a vector of buffers to the destination. This uses sendmsg() when available to perform a gathered write. If IOV_MAX is reached, a fallback will be used.

SYNOPSIS

ssize_t
mongoc_socket_sendv (mongoc_socket_t *sock,
                     mongoc_iovec_t  *iov,
                     size_t           iovcnt,
                     int64_t          expire_at);

PARAMETERS

sock
A mongoc_socket_t \&.

iov
A mongoc_iovec_t.

iovcnt
A size_t containing the number of elements in iov.

expire_at
A int64_t with absolute timeout in monotonic time. The monotonic clock is in microseconds and can be fetched using bson_get_monotonic_time(3) \&.

DESCRIPTION

Sends a vector of buffers to the destination. This uses sendmsg(3) when available to perform a gathered write. If IOV_MAX is reached, a fallback will be used.

RETURNS

the number of bytes sent on success, or -1 on failure and errno is set.

  • mongoc_socket_send (3) - Sends buflen bytes in buf to the destination. If a timeout expired, the number of bytes sent will be returned or -1 if no bytes were sent.
  • mongoc_socket_setsockopt (3) - This is a helper function for setsockopt().
  • mongoc_socket_accept (3) - This function is a wrapper around the BSD socket accept() interface. It allows for more portability between UNIX-like and Microsoft Windows platforms.
  • mongoc_socket_bind (3) - This function is a wrapper around the BSD socket bind() interface. It provides better portability between UNIX-like and Microsoft Windows platforms.
  • mongoc_socket_close (3) - This function is a wrapper around the BSD socket shutdown() interface. It provides better portability between UNIX-like and Microsoft Windows platforms.
  • mongoc_socket_connect (3) - This function is a wrapper around the BSD socket connect() interface. It provides better portability between UNIX-like and Microsoft Windows platforms.
  • mongoc_socket_destroy (3) - This function releases all resources associated with a mongoc_socket_t. This should be called when you are no longer using the socket.
  • mongoc_socket_errno (3) - This function returns the currently captured errno for a socket. This may be useful to check was the last errno was after another function call has been made that clears the threads errno variable.
  • mongoc_socket_getnameinfo (3) - This is a helper around getting the local name of a socket. It is a wrapper around getpeername() and getnameinfo().
  • mongoc_socket_getsockname (3) - Retrieves the socket name for sock. The result is stored in addr. addrlen should be the size of the addr when calling this.
  • mongoc_socket_listen (3) - This function is similar to the BSD sockets listen() function. It is meant for socket servers.
  • mongoc_socket_new (3) - Creates a new mongoc_socket_t structure. This calls socket() underneath to create a network socket.
  • mongoc_socket_recv (3) - This function performs a recv() on the underlying socket.
  • mongoc_socket_t (3) - Portable socket abstraction
  • mongoc_server_description_destroy (3) - This function cleans up all memory associated with the given server description.
