This article provides information about <function>Gestalt</function>
|
|
under ROMlib. Since <application>Executor</application> and the
|
|
Carbonless Copies Runtime System both use ROMlib, this information
|
|
also applies to them.

<para>
|
|
PageMaker 4.2 calls <function>Gestalt</function> with the
|
|
<constant>gestaltAliasMgrAttr</constant> selector and if
|
|
<function>Gestalt</function> returns <returnvalue>noErr</returnvalue>,
|
|
proceeds to use the Alias Manager, even the response is
|
|
<returnvalue>0</returnvalue>. PageMaker 4.2 will not use the Alias
|
|
Manager if in this case <function>Gestalt</function> returns
|
|
<returnvalue>gestaltUndefSelectorErr</returnvalue>. PageMaker 4.2's
|
|
use of <function>Gestalt</function> doesn't appear to be within spec
|
|
(IMVI), but that's just another difference where ROMlib has to do what
|
|
the Mac does, rather than what the specifications suggest.

<para>
|
|
MacInTax '93 does the same thing with the Edition Manager that
|
|
PageMaker does with the Alias Manager. Claris Works does the same
|
|
thing with Apple Events. After ARDI saw three instances of this
|
|
behavior ARDI stopped keeping track. Because of such behavior, there
|
|
are a number of selectors that ROMlib deliberately fails to recognize.
|
|
ROMlib does this when its support for the queried functionality is
|
|
incomplete. Here are the selectors that ROMlib deliberately fails to
|
|
recognize:

ROMlib fails to recognize the following four selectors unless they are
|
|
specifically enabled by the "pretend" options (Pretend Help, Pretend
|
|
Edition, Pretend Script, Pretend Alias). The pretend options can be
|
|
enabled in the preferences panel or via a configuration file.

ARDI has added one special <function>gestalt</function> selector,
|
|
<constant>gestaltPHYSICAL</constant> ('<literal>MUL8</literal>'). It
|
|
returns the address of a routine that behaves just like
|
|
<function>Gestalt</function>, but provides access to a completely
|
|
different set of tables. These tables contain information about the
|
|
environment in which <application>Executor</application> is running
|
|
instead the emulated environment that
|
|
<application>Executor</application> provides.
