|
|
|
|
Routine Description:
|
|
|
|
Return a list of all procedures which conform to the specified dispatch
|
|
table flags.
|
|
|
|
Arguments:
|
|
|
|
DTableEntryList - A pre-allocated iterator for receiving the list of
|
|
dispatch table entries.
|
|
Flags - flags which determine what entries will be picked up.
|
|
|
|
Return Value:
|
|
|
|
A count of the number of procedures in the list.
|
|
|
|
Notes:
|
|
|
|
The flags field is a filter for the dispatch table entries. Only those
|
|
dispatch table entries which have conforming properties are returned in
|
|
the list.
|
|
There are 2 types of entries:
|
|
normal (call with DTF_NONE) and interpreter (call with DTF_INTERPRETER).
|
|
The way it works is that
|
|
- call with DTF_NONE returns DTF_NONEs or DTF_PICKLING_PROCs
|
|
- call with DTF_INTERPRETER returns DTF_INTERPRETERs or DTF_PICKLING_PROCs
