int Ns_ConnReturnOpenFile( Ns_Conn *conn, int status, char *type, int fd, int len );
The Ns_ConnReturnOpenFd function is the same as Ns_ConnReturnFile except that it takes an fd
argument instead of a file name, and it requires an additional length argument. It returns the entire contents of the given file to the client. Ns_ConnReturnOpenFd returns a status of NS_OK or NS_ERROR.
