X-Windows Enumeration

Hi,

I'm new to x-windows system and I have a few questions:

1. How can I write a C program to enumerate all the windows on the local and remote computers? In other words: How can I create a list of all the windows in the system (maximized/minimized/active/not active ....)?

2. How can I recognize events like keystrokes and mouse events?

3. How can I get the mouse cursor position?

All these things must be done in C.

Any help appreciated.
Thank's!

ppmtobmp(1)						      General Commands Manual						       ppmtobmp(1)

NAME

       ppmtobmp - convert a portable pixmap into a BMP file

SYNOPSIS

       ppmtobmp [-windows] [-os2] [-bpp=bits_per_pixel] [ppmfile]

DESCRIPTION

       Reads a portable pixmap as input.  Produces a Microsoft Windows or OS/2 BMP file as output.

OPTIONS

       All options can be abbreviated to their shortest unique prefix and you can use a double dash in place of the single dash, GNU-style.

       -windows
	      Tells the program to produce a Microsoft Windows BMP file.  (This is the default.)

       -os2   Tells the program to produce an OS/2 BMP file.  (Before August 2000, this was the default).

       -bpp   This  determines how many bits per pixel you want the BMP file to contain.  Only 1, 4, 8, and 24 are possible.  By default, ppmtobmp
	      chooses the smallest number with which it can represent all the colors in the input image.  If you specify a  number  too  small	to
	      represent  all  the  colors  in the input image, ppmtobmp tells you and terminates.  You can use ppmquant or ppmdither to reduce the
	      number of colors in the image.

NOTES

       To get a faithful reproduction of the input image, the maxval of the input image must be 255.  If it is something else, ppmtobmp the colors
       in the BMP file may be slightly different from the colors in the input.

       Windows icons are not BMP files.  Use ppmtowinicon to create those.
