.SH "DESCRIPTION"
.sp
.if n \{\
.RS 4
.\}
.nf
The XIQueryPointer function returns the root window the
device\*(Aqs pointer is logically on and the pointer coordinates
relative to the root window\*(Aqs origin\&. If XIQueryPointer returns
False, the pointer is not on the same screen as the specified
window, and XIQueryPointer returns None to child_return and
zero to win_x_return and win_y_return\&. If XIQueryPointer
returns True, the pointer coordinates returned to win_x_return
and win_y_return are relative to the origin of the specified
window\&. In this case, XIQueryPointer returns the child that
contains the pointer, if any, or else None to child_return\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
XIQueryPointer returns the current logical state of the buttons
buttons_return\&. The keyboard paired with the master pointer is
selected to obtain the data for modifiers_return and
group_return\&.
.fi
.if n \{\

.\}
.sp
.if n \{\

.\}
.nf
The mask field in buttons_return is dynamically allocated and
must be freed by the caller\&.
.fi
.if n \{\

.sp
.if n \{\

.nf
XIQueryPointer is identical to XQueryPointer but specifies the
device explicitly\&.

XIQueryPointer can generate a BadDevice and a BadWindow error\&.

.SH "DIAGNOSTICS"

BadDevice
       An invalid device was specified\&. The device does not
       exist or is not a pointer device\&.

       A value for a Window argument does not name a defined
