NAME

       XcmsCCCOfColormap, XcmsSetCCCOfColormap - query and modify CCC of a colormap

SYNTAX

       XcmsCCC XcmsCCCOfColormap(Display *display, Colormap colormap);

       XcmsCCC XcmsSetCCCOfColormap(Display *display, Colormap colormap, XcmsCCC ccc);

ARGUMENTS

       display   Specifies the connection to the X server.

       ccc       Specifies the CCC.

       colormap  Specifies the colormap.

DESCRIPTION

       The  XcmsCCCOfColormap  function  returns the CCC associated with the specified colormap.  Once obtained,
       the CCC attributes can be queried or modified.  Unless the CCC associated with the specified colormap  is
       changed with XcmsSetCCCOfColormap, this CCC is used when the specified colormap is used as an argument to
       color functions.

       The XcmsSetCCCOfColormap function changes the CCC associated with the specified colormap.  It returns the
       CCC  previously associated with the colormap.  If they are not used again in the application, CCCs should
       be freed by calling XcmsFreeCCC.  Several colormaps may share the  same  CCC  without  restriction;  this
       includes  the  CCCs generated by Xlib with each colormap.  Xlib, however, creates a new CCC with each new
       colormap.
