.SH NAME
XkbGetKeyVirtualModMap \- Obtain the virtual modifier map (the vmodmap array) 
for a subset of the keys in a keyboard description
.SH SYNOPSIS

.SH ARGUMENTS
.TP
.I dpy
connection to server
.TP
.I first
keycode of first key to fetch
.TP
.I num
number of keys for which virtual mod maps are desired
.TP
.I xkb
Xkb description where results will be placed
.SH DESCRIPTION
.LP
.I XkbGetKeyVirutalModmap 
sends a request to the server to obtain the virtual modifier mappings for 
.I num 
keys on the keyboard starting with key 
.I first. 
It waits for a reply and returns the virtual modifier mappings in the
.I server->vmodmap 
array of 
.I xkb. 
If successful, 
.I XkbGetKeyVirtualModMap 
returns Success. The 
.I xkb 
parameter must be a pointer to a valid Xkb keyboard description.

If the 
.I server 
map in the 
.I xkb 
parameter has not been allocated, 
.I XkbGetKeyVirtualModMap 
allocates and initializes it before obtaining the virtual modifier mappings.

If the server does not have a compatible version of Xkb, or the Xkb extension 
has not been properly initialized, 
.I XkbGetKeyVirtualModMap 
returns BadMatch. If 
.I num 
is less than 1 or greater than XkbMaxKeyCount, 
.I XkbGetKeyVirtualModMap 
returns BadValue. If any allocation errors occur, 
.I XkbGetKeyVirtualModMap 
returns BadAlloc.
.SH "RETURN VALUES"
.TP 15
Success
The 
.I XkbGetKeyVirutalModmap 
function returns Success following a successful reply from the server to obtain 
the virtual modifier mappings for 
.I num 
keys on the keyboard starting with key 
.I first. 
.SH DIAGNOSTICS
