I'm proposing my HKEY_CLASSES_ROOT implementation patches for review. Feel free to comment. So far, I've written code for all functions except for the RegEnum family.
General description:
HKCR handles are special. All wine handles have the two lowest bits zero'd. HKCR handles are masked. 10b specifically. They have their own table separate from the generic handle table. An HKCR handle has an HKCU handle and an HKLM handle below it. Access mask and a string representing the path are also needed since the handle has to attempt to reopen previously failed openings at certain stages.
First patch: specially handles HKCR handles WITHOUT affecting the general behavior. The end result is still the exact same. Patch provides a foundation for the rest. Second patch: added path management Third patch: added HKCU
Here's a quick description of each function:
create_hkcr_struct: allocates the memory needed for the struct, adds it to the table and gives back a pointer to it get_hkcr_path: given an HKCR handle and a subkey string, prepares a subkey string representing the same subkey rooted at HKLM/HKCU. create_hkcr: RegCreateKeyEx open_hkcr: RegOpenKeyEx resolve_hkcr: checks the HKCR handle, tries to reopen previously failed internal handles, gives back HKCU first if available then HKLM close_hkcr: deallocates path and struct, removes struct from table.
