PR_ConnectContinue
==================
Syntax
------
.. code::
#include <prio.h>
PRStatus PR_ConnectContinue(
PRFileDesc *fd,
PRInt16 out_flags);
Parameters
~~~~~~~~~~
The function has the following parameters:
``fd``
A pointer to a :ref:`PRFileDesc` object representing a socket.
``out_flags``
The out_flags field of the poll descriptor returned by
`PR_Poll() <PR_Poll>`__.
Returns
~~~~~~~
- If the nonblocking connect has successfully completed,
PR_ConnectContinue returns PR_SUCCESS.
- If PR_ConnectContinue() returns PR_FAILURE, call PR_GetError():
- PR_IN_PROGRESS_ERROR: the nonblocking connect is still in
progress and has not completed yet. The caller should poll the file
descriptor for the in_flags PR_POLL_WRITE|PR_POLL_EXCEPT and retry
PR_ConnectContinue later when PR_Poll() returns.
- Other errors: the nonblocking connect has failed with this
error code.
Description
-----------
Continue a nonblocking connect. After a nonblocking connect is initiated
with PR_Connect() (which fails with PR_IN_PROGRESS_ERROR), one should
call PR_Poll() on the socket, with the in_flags PR_POLL_WRITE \|
PR_POLL_EXCEPT. When PR_Poll() returns, one calls PR_ConnectContinue()
on the socket to determine whether the nonblocking connect has completed
or is still in progress. Repeat the PR_Poll(), PR_ConnectContinue()
sequence until the nonblocking connect has completed.
