Maybe this helps. It is a routine that sends one command and tries to
wait for its response from the rc-interface over a socket. I have used
it successfully in the past.

void vlc_rc( int fd, int repeat, char *cmd, size_t len, unsigned long sleep )
    int i;
    int result = 0;
    char buff[255];

    for( i=0; i<repeat; i++)
        write( fd, cmd, len );
        write( fd, NL, 2 );
        usleep( sleep );
        do {
            memset( &buff[0], 0, 255);
            result = read( fd, &buff[0], 255 );
            buff[254] = '\0';
            printf( "[%d] %s", i, &buff[0] );
        } while( result > 0 );
    printf( "DONE\r\n" );

Kind regards,
