HOW RECALLS WORK:
|
|
|
|
The problem:
|
|
Users want the ability to change parameters of the called function
|
|
from inside their handler.
|
|
The solution:
|
|
1) Mark as "recall"
|
|
2) Recall the function
|
|
3) => SH's hook func gets called:
|
|
4) The first iterator points at the first hook the last hookfunc didn't execute yet
|
|
5) does all iteration and returns normally
|
|
6) The user's handler returns immediately
|
|
7) The hook func returns immediately as well
|
|
|
|
Also note that the recalled hookfunc starts with the status the recalling hookfunc
|
|
ended with. The last handler (doing the recall) is also able to specify its own
|
|
META_RES.
