XkbCopyKeyTypes(3) XKB FUNCTIONS XkbCopyKeyTypes(3)NAMEXkbCopyKeyTypes - Copy more than one XkbKeyTypeRec structure
SYNOPSIS
Status XkbCopyKeyTypes ( from, into, num_types )
XkbKeyTypePtr from;
XkbKeyTypePtr into;
int num_types;
ARGUMENTS
- from pointer to array of XkbKeyTypeRecs to copy
- into pointer to array of XkbKeyTypeRecs to change
- num_types
number of types to copy
DESCRIPTIONXkbCopyKeyTypes copies num_types XkbKeyTypeRec structures from the
array specified by from into the array specified by into. It is
intended for copying between, rather than within, keyboard descrip‐
tions, so it doesn't check for overlaps. The same rules that apply to
the from and into parameters in XkbCopyKeyType apply to each entry of
the from and into arrays of XkbCopyKeyTypes. If any allocation errors
occur while copying from to into, XkbCopyKeyTypes returns BadAlloc.
Otherwise, XkbCopyKeyTypes copies from to into and returns Success.
RETURN VALUES
Success The XkbCopyKeyTypes function returns Success when there
are no allocation errors.
STRUCTURES
Key types are used to determine the shift level of a key given the cur‐
rent 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;
