TYPE
Attribute
The TYPE
attribute defines the type of filter. The allowed
filter types are as follows. If no TYPE
attribute is
specified, STANDARD
is assumed.
-
STANDARD
-
A standard filter. See Generating Standard Filters
-
AUXILIARY
-
An auxiliary filter. See Generating Auxiliary Filters
-
WEAK
-
A weak standard filter. Weak filters are identical to standard filters at runtime. At link-edit time, if unused dependency processing is active, a weak filter symbol from a dependency can be ignored in favor of the same symbol from the target filtee. Weak filters are the preferred type when using filters to provide backward compatibility when code moves between libraries. See Generating Weak Filters.
