.Sh DESCRIPTION
|
|
These functions extract and use capabilities from a keyboard capability data
|
|
base, usually
|
|
.Pa /usr/share/misc/keycap.pcvt ,
|
|
the format of which is described in
|
|
.Xr keycap 5 .
|
|
.Pp
|
|
The
|
|
.Fn kgetent
|
|
function
|
|
extracts the entry for keyboard mapping
|
|
.Fa name
|
|
into the buffer at
|
|
.Fa bp .
|
|
The
|
|
.Fa bp
|
|
argument
|
|
should be a character buffer of size
|
|
1024 and must be retained through all subsequent calls to
|
|
.Fn kgetnum ,
|
|
.Fn kgetflag ,
|
|
and
|
|
.Fn kgetstr .
|
|
The
|
|
.Fn kgetent
|
|
function
|
|
returns \-1 if none of the
|
|
.Nm keycap
|
|
data base files could be opened,
|
|
0 if the map name given does not have an entry,
|
|
and 1 if all goes well.
|
|
.Pp
|
|
The
|
|
.Fn kgetnum
|
|
function
|
|
gets the numeric value of capability
|
|
.Fa id ,
|
|
returning \-1 if is not given for the map.
|
|
.Pp
|
|
The
|
|
.Fn kgetflag
|
|
function
|
|
returns 1 if the specified capability is present in
|
|
the map's entry, 0 if it is not.
|
|
.Pp
|
|
The
|
|
.Fn kgetstr
|
|
function
|
|
returns the string value of the capability
|
|
.Fa id ,
|
|
places it in the buffer at
|
|
.Fa area ,
|
|
and advances the
|
|
.Fa area
|
|
pointer.
|
|
The
|
|
.Fn kgetstr
|
|
function
|
|
returns
|
|
.Dv NULL
|
|
if the capability was not found.
