mongoc_socket_recv: This function performs a recv() on the underlying socket.

NAME

mongoc_socket_recv() - This function performs a recv() on the underlying socket.

SYNOPSIS

ssize_t
mongoc_socket_recv (mongoc_socket_t *sock,
                    void            *buf,
                    size_t           buflen,
                    int              flags,
                    int64_t          expire_at);

PARAMETERS

sock
A mongoc_socket_t \&.

buf
A buffer to read into.

buflen
A size_t with the number of bytes to receive.

flags
flags for recv(3) \&.

expire_at
A int64_t with the time to expire in monotonic time using bson_get_monotonic_time(3) , which is in microseconds.

DESCRIPTION

This function performs a recv(3) on the underlying socket.

RETURNS

The number of bytes received on success, 0 on stream closed, and -1 if there was a failure and errno is set.

  • 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_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_sendv (3) - 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.
  • mongoc_socket_setsockopt (3) - This is a helper function for setsockopt().
  • mongoc_socket_t (3) - Portable socket abstraction
  • mongoc_server_description_destroy (3) - This function cleans up all memory associated with the given server description.
