Routine Description:
This routine updates placed instances within a given area with data from
their templates.
Arguments:
AreaResRef - Supplies the resource name of the area to display.
ResMan - Supplies a reference to the resource manager instance to use in
order to load any associated resource data.
TextOut - Supplies the text output interface.
ObjectTypeMask - Supplies the mask of object types to update templates for.
TemplateNames - Supplies the RESREF names of templates that are to be
updated.
ExcludeFields - Supplies a list of fields that are to be excluded from
copying even if they are present in the template.
Return Value:
None. An std::exception is raised on failure.
Environment:
User mode.
