I have been doing some winsock programing recently when I encounted this peice of code:
error=function(local,(sockaddr*) &server,sizeof(server);
What I am confused about is the ...(sockaddr*) &server... part. What is the meaning of this?

question:c++ syntax, (struct*) variable_of_type_struct?

(note:this is a question about syntax, not winsock. I am just using winsock as an example of where it has occured)

&server takes the address of the server variable. The (sockaddr*) parts casts the address to be of type sockaddr*.

Presumably because the function wants an argument of type sockaddr*, but the type of server is something other than sockaddr.
