# 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.
