       XReadBitmapFile, XWriteBitmapFile, XCreatePixmapFromBitmapData, XCreateBitmapFromData - manipulate bitmaps

       bitmap	 Specifies the bitmap.

		 Returns the bitmap that is created.

       d	 Specifies the drawable that indicates the screen.

       data	 Specifies the data in bitmap format.

       data	 Specifies the location of the bitmap data.

       depth	 Specifies the depth of the pixmap.

       display	 Specifies the connection to the X server.

       bg	 Specify the foreground and background pixel values to use.

       filename  Specifies the file name to use.  The format of the file name is operating-system dependent.

       height	 Specify the width and height.

		 Return the width and height values of the read in bitmap file.

       y_hot	 Specify where to place the hotspot coordinates (or -1,-1 if none are present) in the file.

		 Return the hotspot coordinates.

       The function reads in a file containing a bitmap.  The ability to read other than the standard format is implementation dependent.  If the
       file cannot be opened, returns If the file can be opened but does not contain valid bitmap data, it returns If insufficient working storage
       is allocated, it returns If the file is readable and valid, it returns

       returns the bitmap's height and width, as read from the file, to width_return and height_return.  It then creates a pixmap of the appropri-
       ate size, reads the bitmap data from the file into the pixmap, and assigns the pixmap to the caller's variable bitmap.  The caller must
       free the bitmap using when finished.  If name_x_hot and name_y_hot exist, returns them to x_hot_return and y_hot_return; otherwise, it
       returns -1,-1.

       can generate and errors.

       The function writes a bitmap out to a file in the X version 11 format.  If the file cannot be opened for writing, it returns If insuffi-
       cient memory is allocated, returns otherwise, on no error, it returns If x_hot and y_hot are not -1, -1, writes them out as the hotspot
       coordinates for the bitmap.

       can generate and errors.

       The function creates a pixmap of the given depth and then does a bitmap-format of the data into it.  The depth must be supported by the
       screen of the specified drawable, or a error results.

       can generate and errors.

       The function allows you to include in your C program (using #include) a bitmap file that was written out by (X version 11 format only)
       without reading in the bitmap file.  The following example creates a gray bitmap:

       #include "gray.bitmap"
       Pixmap bitmap;
       bitmap = XCreateBitmapFromData(display, window, gray_bits,
		  gray_width, gray_height);

       If insufficient working storage was allocated, returns It is your responsibility to free the bitmap using when finished.

       can generate a error.

       The server failed to allocate the requested resource or server memory.

       A value for a Drawable argument does not name a defined Window or Pixmap.

       An	 window is used as a Drawable.
