PR_GetConnectStatus
===================
Get the completion status of a nonblocking connection.
Syntax
------
.. code::
PRStatus PR_GetConnectStatus(const PRPollDesc *pd);
Parameter
~~~~~~~~~
The function has the following parameter:
``pd``
A pointer to a ``PRPollDesc`` satructure whose ``fd`` field is the
socket and whose ``in_flags`` field must contain ``PR_POLL_WRITE``
and ``PR_POLL_EXCEPT``.
Returns
~~~~~~~
The function returns one of these values:
- If successful, ``PR_SUCCESS``.
- If unsuccessful, ``PR_FAILURE``. The reason for the failure can be
retrieved via :ref:`PR_GetError`.
If :ref:`PR_GetError` returns ``PR_IN_PROGRESS_ERROR``, the nonblocking
connection is still in progress and has not completed yet.Other errors
indicate that the connection has failed.
Description
-----------
After :ref:`PR_Connect` on a nonblocking socket fails with
``PR_IN_PROGRESS_ERROR``, you may wait for the connection to complete by
calling :ref:`PR_Poll` on the socket with the ``in_flags``
``PR_POLL_WRITE`` \| ``PR_POLL_EXCEPT``. When :ref:`PR_Poll` returns, call
:ref:`PR_GetConnectStatus` on the socket to determine whether the
nonblocking connect has succeeded or failed.
