XkbCopyKeyType(3)         XKB FUNCTIONS         XkbCopyKeyType(3)



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. Otherwise, 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
