nn_connect(3compat)
NAME
nn_connect - connect to remote peer (compatible API)
SYNOPSIS
DESCRIPTION
The nn_connect()
function arranges for the socket sock to
initiate connection to a peer at the address specified by url.
An identifier for this socket’s association with the url is
returned to the caller on success.
This identifier can be used with
nn_shutdown()
to
remove the association later.
This function is provided for API compatibility with legacy libnanomsg. Consider using the relevant modern API instead. |
The connect operation is performed asynchronously, and may not have completed before this function returns control to the caller. |
Only transports supported by legacy libnanomsg may be
used with this function.
In particular, only the schemes tcp:// , ipc:// , inproc:// , and ws:// are
supported with this function.
(Use the modern API to use other schemes.)
|
RETURN VALUES
This function returns a positive identifier success, and -1 on error.
ERRORS
ECONNREFUSED
|
The connection attempt was refused. |
EBADF
|
The socket sock is not open. |
EINVAL
|
An invalid url was supplied. |
