       display	 Specifies the connection to the X server.

		 Returns the number of pixmap formats that are supported by
		 the display.

		 Specifies the appropriate screen number on the host server.

       The function returns an array of structures that describe the types of
       Z format images supported by the specified display.  If insufficient
       memory is available, returns NULL.  To free the allocated storage for
       the structures, use

       The macro specifies the required byte order for images for each scan‐
       line unit in XY format (bitmap) or for each pixel value in Z format.

       The macro returns or to indicate whether the leftmost bit in the bitmap
       as displayed on the screen is the least or most significant bit in the

       The macro returns the number of bits that each scanline must be padded.

       The macro returns the size of a bitmap's scanline unit in bits.

       The macro returns the height of the specified screen in pixels.

       The macro returns the height of the specified screen in millimeters.

       The macro returns the width of the screen in pixels.

       The macro returns the width of the specified screen in millimeters.

       The structure provides an interface to the pixmap format information
       that is returned at the time of a connection setup.  It contains:

       typedef struct {
	       int depth;
	       int bits_per_pixel;
	       int scanline_pad;
       } XPixmapFormatValues;
