Dev Notes:
|
|
To define a redirected provider, call FDefineProvTypeFuncPointers(...).
|
|
Any hProv, hKey, or hHash created using that dwProvType after will
|
|
be redirected. Any provider not in the list of redirected providers
|
|
will fall through to CAPI. ReDir's handles are fully compatible with
|
|
direct calls to CAPI.
|
|
|
|
You are not required to undefine a provider you define -- ReDir will
|
|
clean up the table during PROCESS_DETACH. However, if you
|
|
wish to clean up a dwProvType you previously defined, call
|
|
FUndefineProvTypeFuncPointers(...).
|
|
|
|
|
|
|
|
WARNING:
|
|
Reference counting is not applied to the defined providers. That
|
|
is, if you remove a provider definition and then attempt to use
|
|
an {hKey, hProv, hHash} that was used with that provider, ReDir will
|
|
not have a valid function table.
|
|
|
|
|
|
|
|
MultiThreading:
|
|
Critical sections are applied to all functions where necessary, and
|
|
this library should be fully multithread-safe.
|
|
|
|
|
|
|
|
CryptSetProvider availability:
|
|
CryptSetProvider{A,W} is not available to non-CAPI providers. The
|
|
functions return FALSE if not pointing to AdvAPI's CAPI.
|
|
|
|
|
|
|
|
Wide char APIs:
|
|
Win95 doesn't support Wide APIs, and real ADVAPI doesn't export them.
|
|
Thus, the easiest thing to do was to not try an load them, in any case.
|
|
This means ReDir doesn't support the Wide APIs, even on NT. Could change
|
|
to use an OS check before loading...?
|
|

|
|
// force us away from either just yet...
