Function Documentation

int changeUserGroupID (    )

used to degrade the user and group. this is used for security reasons Returns: 0 on success, -1 otherwise Definition at line 308 of file server.c. Referenced by svMain().

int newServerSocket (  unsigned short int    port_num )

create a new server socket. Creates and binds a new socket which is then initalized for accepting connections (listen). This function will move to a separate module until the next release. Parameters: port_num  number of port to bind Returns: returns -1 on failure and the new socket's descriptor on success Definition at line 77 of file server.c. Referenced by svMain().

int svCloseConnection (  ConnHandler    ch )

closes a client connection and terminates the corresponding ConnHandler the ConnHandler stored in the list's current active node is. Terminates the given connection handler and removes the corresponding socket from the set of active sockets. Definition at line 100 of file server.c.

Variable Documentation

fd_set sock_recv_set

set of sockets currently active. Todo: : put these into a structure (create a server state structure, opaque Server data type) Definition at line 57 of file server.c.
