NAME
       EZ_AddInput, EZ_RemoveInput - register/remove input handlers

SYNOPSIS
       #include	<EZ.h>

       EZ_Input	*EZ_AddInput(int fd, int mask,
		     EZ_InputCallBack callback,	void *data)

       void EZ_RemoveInput(EZ_Input *input)

ARGUMENTS
       fd  Specifies a file descriptor.

       mask Specifies the mask that indicates a	read, write, or	exception con-
       dition. It must be ORed	from  EZ_READABLE_MASK,	 EZ_WRITABLE_MASK  and
       EZ_EXCEPTION_MASK.

       callback	 Specify the procedure to be invoked when input	is ready.

       data  Specifies the argument that is to be passed to callback  when in-
       voked.

       input  Specifies	a EZ_Input handler.

DESCRIPTION
       EZ_AddInput registers an	input handler to the EZWGL library.

       EZ_RemoveInput removes a	previousely registered input handler.

       EZ_InputCallBack	is a procedure of type
	 void (*inputCallback)(void *object, void *data, int fd, int mask);

       Here is a simple	input handler that reads from the standard  input  and
       insert the input	in a text widget.

       static void readStdin(EZ_Input *id, void	*data, int fd, int mask)
       {
	 EZ_Widget *tw = (EZ_Widget *)data;
	 char buf[1024];
	 int n;
	 if(mask & EZ_READABLE_MASK)
	   {
	     n = read(fd, buf, 1023);
	     if(n > 0)
	    {
	      buf[n] = 0;
	      EZ_TextEndOfBuffer(tw);
	      EZ_TextInsertString(tw,buf);
	    }
	   }
       }
