Name
valid_socket - protects the socket efunctions.
Synopsis
int valid_socket( object caller, string function,
mixed *info );
Description
Each of the socket efunctions calls valid_socket() prior to executing. If valid_socket returns 0, then the socket efunction fails. If valid_socket returns 1, then the socket efunction attempts to succeed. The first argument 'caller' is the object that called the socket efunction. The second argument is the name of the socket efunction that is being called (e.g. socket_write() or socket_bind()). The third argument is an array of information. The first element of the array (when applicable) is file descriptor being referenced. The second element of the array is the owner of the socket (object). The third element of the array is the address (string) of the remote end of the socket. The fourth element of the array is the port number associated with the socket.
