Corrosponding windows API is
DWORD InternetAttemptConnect(DWORD dwReserved)
is there any API/function call for doing this on MAC OSX.
There are three ways to do this on Mac OS X.
1. Many users have the system configured to "dial on demand". Thus,
all you need to do in order to trigger a dial is to send some
traffic. See DTS Technote 1145 "Living in a Dynamic TCP/IP
Environment" for more details.

2. If the system is not configured to dial on demand, you can force a
dial using one of two APIs. The supported mechanism is to use the
OT/PPP API, as described in the Open Transport SDK.

This API originated on traditional Mac OS but works fine on Mac OS X
for applications that only need limited control of the modem.
3. For more sophisticated control over the dialling process, you can
use on unsupported API, namely "ppplib". Here's some info I wrote
up about "ppplib" for another developer.
You can use the "ppplib" code from the Darwin PPP sources. You can
find a quick tutorial on this on the following web page.
<http://www.cocoadevcentral.com/tutorials/showpage.php?show=00000026.php>
There's also been several discussions of this on the MacNetworkProg
mailing list. If you follow the links from the mailing list's web
page, you will find a searchable archive of that material.

The drawback to using "ppplib" is that it's not officially supported
by Apple. Here's a statement that the manager of our network
engineering team posted to the list just recently.
Let me emphasis the PPPLib code does not defines an API (Application
Programming Interface). This is just a sample code that is part of
Darwin but it is not part of Mac OS X. Apple is not making any
guaranty the PPPLib code does actually work now or will work in
future releases of Mac OS X.
Obviously, we are aware of the usefulness of PPPLib and we will try
to keep PPPLib working.
Use at your own risk!

Manager,
Networking Team Apple
Apple is aware of these problems and intends to rectify them,
probably by releasing a new, CF-friendly, PPP API in a future major
release of Mac OS X.
