+.TP

+description from which new values are taken
+.SH DESCRIPTION
+.LP
+There are two ways to make changes to map components: either change a local copy
+of the keyboard map and
+call
+.I XkbSetMap
+to send the modified map to the server, or, to reduce network traffic, use an
+XkbMapChangesRec structure
+and call
+.I XkbChangeMap.
+
+Use
+.I XkbSetMap
+to send a complete new set of values for entire components (for example, all
+symbols, all actions, and so
+on) to the server. The
+.I which
+parameter specifies the components to be sent to the server, and is a bitwise
+inclusive OR of the masks
+listed in Table 1. The
+.I xkb
+parameter is a pointer to an XkbDescRec structure and contains the information
+to be copied to the server.
+For each bit set in the
+.I which
+parameter,
+.I XkbSetMap
+takes the corresponding structure values from the
+.I xkb
+parameter and sends it to the server specified by
+.I dpy.
+
+If any components specified by
+.I which
+are not present in the
+.I xkb
+parameter,
+.I XkbSetMap
+returns False. Otherwise, it sends the update request to the server and returns
+True.
+.I XkbSetMap
+can generate BadAlloc, BadLength, and BadValue protocol errors.
+
+Key types, symbol maps, and actions are all interrelated; changes in one require
+changes in the others. Xkb
+provides functions to make it easier to edit these components and handle the
+interdependencies. Table 1
+lists these helper functions and provides a pointer to where they are defined.

+The
+.I changed
+field identifies the map components that have changed in an XkbDescRec structure
+and may contain any of the
+bits in Table 1, which are also shown in Table 2. Every 1 bit in
+.I changed
+also identifies which other fields in the XkbMapChangesRec structure contain
+valid values, as indicated in
+Table 2. The
+.I min_key_code
+and
+.I max_key_code
+fields are for reference only; they are ignored on any requests sent to the
+server and are always updated
+by the server whenever it returns the data for an XkbMapChangesRec.

+The complete description of an Xkb keyboard is given by an XkbDescRec. The
+component
+structures in the XkbDescRec represent the major Xkb components.

+The
+.I display
+field points to an X display structure. The
+.I flags field is private to the library: modifying
+.I flags
+may yield unpredictable results. The
+.I device_spec
+field specifies the device identifier of the keyboard input device, or
+XkbUseCoreKeyboard, which specifies the core keyboard device. The
+.I min_key_code
+and
+.I max_key_code
+fields specify the least and greatest keycode that can be returned by the
+keyboard.
+
+Each structure component has a corresponding mask bit that is used in function
+calls to
+indicate that the structure should be manipulated in some manner, such as
+allocating it
+or freeing it. These masks and their relationships to the fields in the
+XkbDescRec are
+shown in Table 3.
