Abstract:
|
||
|
|
|
||
|
|
Routines to query wizard pages from OC DLLs and manage the results.
|
||
|
|
|
||
|
|
No wizard is actually displayed by this routine -- that is up to
|
||
|
|
whoever links to the OC Manager common library.

Routine Description:
|
||
|
|
|
||
|
|
Request wizard pages from OC DLL's, according to ordering and omission
|
||
|
|
rules specified in the master OC inf.
|
||
|
|
|
||
|
|
Pages are returned in the form of wizard page handles in SETUP_REQUEST_PAGES
|
||
|
|
data structures.
|
||
|
|
|
||
|
|
Arguments:
|
||
|
|
|
||
|
|
OcManagerContext - supplies OC Manager context structure, returned by
|
||
|
|
OcInitialize().
|
||
|
|
|
||
|
|
Pages - points to a block of memory that can hold WizPagesTypeMax pointers to
|
||
|
|
SETUP_REQUEST_PAGES structures. On successful completion, that array is
|
||
|
|
filled in with such pointers.
|
||
|
|
|
||
|
|
Return Value:
|
||
|
|
|
||
|
|
Win32 error code indicating outcome.
