NAME

XFreeColormap — delete a colormap and install the default colormap. 

SYNOPSIS

XFreeColormap(display, colormap) Display ∗display; Colormap colormap;

ARGUMENTS

displaySpecifies a connection to an X server; returned from XOpenDisplay(). 

colormapSpecifies the colormap to delete. 

DESCRIPTION

XFreeColormap() destroys the specified colormap, unless it is the default colormap for a screen.  That is, it not only uninstalls colormap from the hardware colormap if it is installed, but also frees the associated memory including the colormap ID. 

XFreeColormap() performs the following processing:

•If colormap is an installed map for a screen, it uninstalls the colormap (see XUninstallColormap()). 

•If colormap is defined as the colormap attribute for a window (by XCreateWindow() or XChangeWindowAttributes()), it changes the colormap attribute for the window to the constant None, generates a ColormapNotify event, and frees the colormap.  The colors displayed with a colormap of None are server-dependent, since the default colormap is normally used. 

For more information, see Volume One, Chapter 7, Color. 

ERRORS

BadColorInvalid colormap.
