NAME

DgInqOpen − Determine which, if any, group is open

SYNOPSIS

C:

DtObject DgInqOpen()

Fortran:

INTEGER∗4 DGQO()

DESCRIPTION

DgInqOpen finds out which group, if any, is currently open.  If more than one group is open, DgInqOpen returns the handle of the most recently opened group (the active group).  Note that there can be at most one group active at any given time.  Most group editing operations are performed on the active group. 

DgInqOpen will return the group name of the currently open group if a group is currently open.  If no group is currently open, DgInqOpen will return DcNullObject <DCNULL>. 

DgInqOpen will always work.
