PR_Bind
=======
Binds an address to a specified socket.
Syntax
------
.. code::
#include <prio.h>
PRStatus PR_Bind(
PRFileDesc *fd,
const PRNetAddr *addr);
Parameters
~~~~~~~~~~
The function has the following parameters:
``fd``
A pointer to a :ref:`PRFileDesc` object representing a socket.
``addr``
A pointer to a :ref:`PRNetAddr` object representing the address to which
the socket will be bound.
Returns
~~~~~~~
The function returns one of the following values:
- Upon successful binding of an address to a socket, ``PR_SUCCESS``.
- If unsuccessful, ``PR_FAILURE``. Further information can be obtained
by calling :ref:`PR_GetError`.
Description
-----------
When a new socket is created, it has no address bound to it. :ref:`PR_Bind`
assigns the specified address (also known as name) to the socket. If you
do not care about the exact IP address assigned to the socket, set the
``inet.ip`` field of :ref:`PRNetAddr` to :ref:`PR_htonl`\ (``PR_INADDR_ANY``).
If you do not care about the TCP/UDP port assigned to the socket, set
the ``inet.port`` field of :ref:`PRNetAddr` to 0.
Note that if :ref:`PR_Connect` is invoked on a socket that is not bound, it
implicitly binds an arbitrary address the socket.
Call :ref:`PR_GetSockName` to obtain the address (name) bound to a socket.
