problem accessing these functions

in a demo tutorial example program i downloaded it has a included .h file and then in the src code it has funtions like

VB Code:

int thedot'h'file::functionname(arguments)
{
        code;
}

i tried calling these functions with

VB Code:

functionname(arguments);

but it didnt work. how can i access these functions?

that looks like a functioin of a class
you'd have to declare something first
thedot'h'file myvar;
myvar.functionname(arguments)

what book is this?

i still dont quite understand what u mean. the structure is called MasterSocket and inside is a void called Listen. how would i access listen?

heres the whole source code.

VB Code:

When posting C/C++ code you should use [ code ] or [ php ] tags, not [ vbcode ]

Code:

---

int main()
{
  // initwinsock is not necessary, this is done automatically
  MasterSocket socket;  // create a mastersocket object
  socket->Listen(80);  // listen to the http port
}
