Thanks!
Your code opens the file sequentially, but the output shows three values in a row, which seems to me the three files are opened simultaneously:
Code:
Connected to server! 
Data returned by the server: 
TEMPERATURE = 60 HUMIDITY = 40 LIGHT = 1 
Data returned by the server: 
TEMPERATURE = 59 HUMIDITY = 50 LIGHT = 2 
Data returned by the server: 
TEMPERATURE = 58 HUMIDITY = 20 LIGHT = 3

1) Is this right? I was thinking pthreads too, but not sure pthreads is the correct way.
2) I assumed this display part is piped in the client side. Can this part be embedded to the echoClient program, i.e. integrated this part into the echoClient program?

Thanks again!

xchangekeyboarddevice

XChangeKeyboardDevice(3X11)											       XChangeKeyboardDevice(3X11)

NAME

       XChangeKeyboardDevice - change which device is used as the X keyboard

SYNOPSIS

       Status XChangeKeyboardDevice(display, device)
	       Display *display;
	       XDevice *device;

ARGUMENTS

       Specifies the connection to the X server.  Specifies the device to be used as the X keyboard.

DESCRIPTION

       The  XChangeKeyboardDevice  request  causes the server to use the specified device as the X keyboard.  The device must have been previously
       opened by the requesting client via XOpenDevice or a BadDevice error will result. The device must support input class Keys, or  a  BadMatch
       error  will  result.   If  the  server implementation does not support using the requested device as the X keyboard, a BadDevice error will
       result.

       If the specified device is grabbed by another client, AlreadyGrabbed is returned.  If the specified device is frozen by a grab  on  another
       device, GrabFrozen is returned. If the request is successful, Success is returned.

       If  the	request  succeeds,  a  ChangeDeviceNotify  event is sent to all clients that have selected that event.	A MappingNotify event with
       request = MappingKeyboard is sent to all clients. The specified device becomes the X keyboard and the old  X  keyboard  becomes	accessible
       through the input extension protocol requests.

       XChangeKeyboardDevice can generate a BadDevice or a BadMatch error.

DIAGNOSTICS

       An  invalid  device  was  specified.   The specified device does not exist, has not been opened by this client via XOpenInputDevice,  or is
       already one of the core X device (pointer or keyboard).	This error may also occur if the server implementation does not support using  the
       specified  device  as  the  X  keyboard.  This error may occur if an XChangeKeyboardDevice request was made specifying a device that has no
       keys.
