       XCreatePixmap, XFreePixmap - create or destroy pixmaps


       Pixmap  XCreatePixmap(Display  *display,  Drawable  d,  unsigned  int  width, unsigned int
              height, unsigned int depth);

       int XFreePixmap(Display *display, Pixmap pixmap);


       d         Specifies which screen the pixmap is created on.

       depth     Specifies the depth of the pixmap.

       display   Specifies the connection to the X server.

       pixmap    Specifies the pixmap.

       height    Specify the width and height, which define the dimensions of the pixmap.


       The XCreatePixmap function creates a pixmap of the width, height, and depth you  specified
       and  returns  a  pixmap ID that identifies it.  It is valid to pass an InputOnly window to
       the drawable argument.  The width and height arguments must  be  nonzero,  or  a  BadValue
       error  results.   The  depth argument must be one of the depths supported by the screen of
       the specified drawable, or a BadValue error results.

       The server uses the specified drawable to determine on which screen to create the  pixmap.
       The pixmap can be used only on this screen and only with other drawables of the same depth
       (see XCopyPlane for an exception to this rule).  The initial contents of  the  pixmap  are

       XCreatePixmap can generate BadAlloc, BadDrawable, and BadValue errors.

       The  XFreePixmap  function  first  deletes  the  association between the pixmap ID and the
       pixmap.  Then, the X server frees the pixmap storage when there are no references  to  it.
       The pixmap should never be referenced again.

       XFreePixmap can generate a BadPixmap error.


       BadAlloc  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.

       BadPixmap A value for a Pixmap argument does not name a defined Pixmap.

       BadValue  Some  numeric  value  falls outside the range of values accepted by the request.
                 Unless a specific range is specified for an argument, the full range defined  by
                 the  argument's type is accepted.  Any argument defined as a set of alternatives
                 can generate this error.
