.TH XkbResizeKeyType __libmansuffix__ __xorgversion__ "XKB FUNCTIONS"
.SH NAME
XkbResizeKeyType \- Change the number of levels in a key type
.SH SYNOPSIS
.HP
.B Status XkbResizeKeyType
.BI "(\^XkbDescPtr " "xkb" "\^,"
.BI "int " "type_ndx" "\^,"
.BI "int " "map_count" "\^,"
.BI "Bool " "want_preserve" "\^,"
.BI "int " "new_num_lvls" "\^);"
.if n .ti +5n
.if t .ti +.5i
.SH ARGUMENTS
.TP
.I \- xkb
keyboard description containing client map to update
.TP
.I \- type_ndx
index in xkb->map->types of type to change
.TP
.I \- map_count
total # of map entries needed for the type
.TP
.I \- want_preserve
True => list of preserved modifiers is necessary
.TP
.I \- new_num_lvls
new max # of levels for type
.SH DESCRIPTION
.LP
.I XkbResizeKeyType
changes the type specified by
.I xkb->map->types[type_ndx],
and reallocates the symbols and actions bound to all keys that use the type, if
necessary.
.I XkbResizeKeyType
updates only the local copy of the types in
.I xkb;
to update the server's copy for the physical device, use
.I XkbSetMap
or
.I XkbChangeMap
after calling
.I XkbResizeKeyType.
The
.I map_count
parameter specifies the total number of map entries needed for the type, and can
be zero or greater. If
.I map_count
is zero,
.I XkbResizeKeyType
frees the existing
.I map
and
.I preserve
entries for the type if they exist and sets them to NULL.
The
.I want_preserve
parameter specifies whether a
.I preserve
list for the key should be created. If
.I want_preserve
is True, the
.I preserve
list with
.I map_count
entries is allocated or reallocated if it already exists. Otherwise, if
.I want_preserve
is False, the
.I preserve
field is freed if necessary and set to NULL.
The
.I new_num_lvls
parameter specifies the new maximum number of shift levels for the type and is
used to calculate and resize the symbols and actions bound to all keys that use
the type.
If
.I type_ndx
does not specify a legal type,
.I new_num_lvls
is less than 1, or the
.I map_count
is less than zero,
.I XkbResizeKeyType
returns BadValue. If
.I XkbResizeKeyType
encounters any problems with allocation, it returns BadAlloc. Otherwise, it
returns Success.
.SH "RETURN VALUES"
.TP 15
Success
The
.I XkbResizeKeyType
function returns Success if
.I type_ndx
specifies a legal type,
.I new_num_lvls
is greater than zero and
.I map_count
is positive.
.SH DIAGNOSTICS
.TP 15
.B BadAlloc
Unable to allocate storage
.TP 15
.B BadValue
An argument is out of range
