* Send the process attach notification to all DLLs the given module
|
|
* depends on (recursively). This is somewhat complicated due to the fact that
|
|
*
|
|
* - we have to respect the module dependencies, i.e. modules implicitly
|
|
* referenced by another module have to be initialized before the module
|
|
* itself can be initialized
|
|
*
|
|
* - the initialization routine of a DLL can itself call LoadLibrary,
|
|
* thereby introducing a whole new set of dependencies (even involving
|
|
* the 'old' modules) at any time during the whole process
|
|
*
|
|
* (Note that this routine can be recursively entered not only directly
|
|
* from itself, but also via LoadLibrary from one of the called initialization
|
|
* routines.)
|
|
*
|
|
* Furthermore, we need to rearrange the main WINE_MODREF list to allow
|
|
* the process *detach* notifications to be sent in the correct order.
|
|
* This must not only take into account module dependencies, but also
|
|
* 'hidden' dependencies created by modules calling LoadLibrary in their
|
|
* attach notification routine.
|
|
*
|
|
* The strategy is rather simple: we move a WINE_MODREF to the head of the
|
|
* list after the attach notification has returned. This implies that the
|
|
* detach notifications are called in the reverse of the sequence the attach
|
|
* notifications *returned*.
