Tk_FreeXId(3TK) Tk Library Procedures Tk_FreeXId(3TK) __________________________________________________________________________________________________________________________________________________NAMETk_FreeXId - make X resource identifier available for reuseSYNOPSIS#include <tk.h> Tk_FreeXId(display, id)ARGUMENTSDisplay *display (in) Display for which id was allocated. XID id (in) Identifier of X resource (window, font, pixmap, cursor, graphics context, or colormap) that is no longer in use. _________________________________________________________________DESCRIPTIONThe default allocator for resource identifiers provided by Xlib is very simple-minded and does not allow resource identifiers to be re- used. If a long-running application reaches the end of the resource id space, it will generate an X protocol error and crash. Tk replaces the default id allocator with its own allocator, which allows identifiers to be reused. In order for this to work, Tk_FreeXId must be called to tell the allocator about resources that have been freed. Tk automatically calls Tk_FreeXId whenever it frees a resource, so if you use procedures like Tk_GetFont, Tk_GetGC, and Tk_GetPixmap then you need not call Tk_FreeXId. However, if you allocate resources directly from Xlib, for example by calling XCreatePixmap, then you should call Tk_FreeXId when you call the corresponding Xlib free proce- dure, such as XFreePixmap. If you don't call Tk_FreeXId then the resource identifier will be lost, which could cause problems if the application runs long enough to lose all of the available identifiers.KEYWORDSresource identifierATTRIBUTESSee attributes(5) for descriptions of the following attributes: +--------------------+-----------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +--------------------+-----------------+ |Availability | SUNWTk | +--------------------+-----------------+ |Interface Stability | Uncommitted | +--------------------+-----------------+NOTESSource for Tk is available on http://opensolaris.org.
