XkbCopyKeyTypes \- Copy more than one XkbKeyTypeRec structure
.SH SYNOPSIS

.BI "int " "num_types" "\^);"

.SH ARGUMENTS
.TP
.I \- from
pointer to array of XkbKeyTypeRecs to copy
.TP
.I \- into
pointer to array of XkbKeyTypeRecs to change
.TP
.I \- num_types
number of types to copy
.SH DESCRIPTION
.LP
.I XkbCopyKeyTypes
copies
.I num_types
XkbKeyTypeRec structures from the array specified by
.I from
into the array specified by
.I into.
It is intended for copying between, rather than within, keyboard descriptions,
so it
doesn't check for overlaps. The same rules that apply to the
.I from
and
.I into
parameters in
.I XkbCopyKeyType
apply to each entry of the
.I from
and
.I into
arrays of
.I XkbCopyKeyTypes.
If any allocation errors occur while copying
.I from
to
.I into, XkbCopyKeyTypes
returns BadAlloc. Otherwise,
.I XkbCopyKeyTypes
copies
.I from
to
.I into
and returns Success.
.SH "RETURN VALUES"
.TP 15
Success
The XkbCopyKeyTypes function returns Success when there are no allocation
errors.
.SH STRUCTURES
.LP
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
.I types
field of the client map, whose total size is stored in
.I size_types,
and whose total number of valid entries is stored in
.I num_types.
Key types are defined using the following structure:
.nf
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;
.fi
.SH DIAGNOSTICS
