XkbKeyType(3)							   XKB FUNCTIONS						     XkbKeyType(3)

NAME

       XkbKeyType - Obtain the index of a key type or the pointer to a key type

SYNOPSIS

       XkbKeyTypePtr XkbKeyType (XkbDescPtr xkb, KeyCode keycode, int group);

ARGUMENTS

       - xkb  Xkb description of interest

       - keycode
	      keycode of interest

       - group
	      group index

DESCRIPTION

       XkbKeyType  returns  a  pointer	to  the key type in the types vector of the client map in xkb corresponding to the given keycode and group
       index.

STRUCTURES

       typedef struct { 			    /* Key Type */
	    XkbModsRec		    mods;	    /* modifiers used to compute shift level */
	    unsigned char	    num_levels;     /* total # shift levels, do not modify directly */
	    unsigned char	    map_count;	    /* # entries in map, preserve (if non-NULL) */
	    XkbKTMapEntryPtr	    map;	    /* vector of modifiers for each shift level */
	    XkbModsPtr		    preserve;	    /* mods to preserve for corresponding map entry */
	    Atom		    name;	    /* name of key type */
	    Atom *		    level_names;    /* array of names of each shift level */
       } XkbKeyTypeRec, *XkbKeyTypePtr;

NAME

       XkbCopyKeyType - Copy one XkbKeyTypeRec structures

SYNOPSIS

       Status XkbCopyKeyType ( from, into )
	     XkbKeyTypePtr from;
	     XkbKeyTypePtr into;

ARGUMENTS

       - from pointer to XkbKeyTypeRec to be copied

       - into pointer to XkbKeyTypeRec to be changed

DESCRIPTION

       XkbCopyKeyType copies the key type specified by from to the key type specified by into.	Both must point to legal XkbKeyTypeRec structures.
       Xkb assumes from and into point to different places. As a result, overlaps can be fatal.  XkbCopyKeyType frees any existing map,  preserve,
       and  level_names in into prior to copying. If any allocation errors occur while copying from to into, XkbCopyKeyType returns BadAlloc. Oth-
       erwise, XkbCopyKeyType copies from to into and returns Success.

STRUCTURES

       Key types are used to determine the shift level of a key given the current state of the keyboard. The set of all possible key types for the
       Xkb keyboard description are held in the types field of the client map, whose total size is stored in size_types, and whose total number of
       valid entries is stored in num_types.  Key types are defined using the following structure:

       typedef struct { 		  /* Key Type */
	   XkbModsRec	     mods;	  /* modifiers used to compute shift level */
	   unsigned char     num_levels;  /* total # shift levels, do not modify directly */
	   unsigned char     map_count;   /* # entries in map, preserve (if non-NULL) */
	   XkbKTMapEntryPtr  map;	  /* vector of modifiers for each shift level */
	   XkbModsPtr	     preserve;	  /* mods to preserve for corresponding map entry */
	   Atom 	     name;	  /* name of key type */
	   Atom *	     level_names; /* array of names of each shift level */
       } XkbKeyTypeRec, *XkbKeyTypePtr;

DIAGNOSTICS

       BadAlloc       Unable to allocate storage
