MODULE: UIProf.h
PURPOSE: Handles low-level manipulation of user profile files Handles user preferences (saved info)
FUNCTIONS:
UserProfileInit() - Initializes the user profile module. The cached profile is initially empty. UserProfileFree() - Frees memory used by the user profile module. UserProfileRead() - Caches the profile for the specified user from permanent storage into a global data structure, for future UserProfileQuery/Enum calls. Call with NULL to clear the cached profile. UserProfileWrite() - Writes the cached profile into permanent storage. UserProfileQuery() - Returns one entry from the cached profile. UserProfileEnum() - Lists all entries in the cached profile. UserProfileSet() - Changes the cached profile. It is generally advisable to immediately precede this call with UserProfileRead, and immediately follow it with UserProfileWrite.
UserPreferenceQuery() - queries a single user preference string. UserPreferenceSet() - saves a single user preference string. UserPreferenceQueryBool() - queries a user preference bool value. UserPreferenceSetBool() - saves a user preference bool value.
COMMENTS:
UserProfile routines:
Under LM30, the profile in $(LANROOT) will only be used if the profile stored in the DS is unavailable.
Be sure to cache a user's profile before calling UserProfileQuery, UserProfileEnum or UserProfileSet. These routines will fail if no profile is currently cached.
The cpszUsername argument is handled differently from different APIs. UserProfileRead and UserProfileWrite use it to specify the user profile to read or write. UserProfileRead will also remember the last username in a static variable whether the call succeeds or not. Null or empty user names clear the stored profile in UserProfileRead, and return NERR_BadUsername in UserProfileWrite. UserProfileQuery, Enum and Set compare cpszUsername with the last username remembered by UserProfileRead. If UserProfileRead has never been called, or if it was last called with a different username (NULL and empty string are equivalent), these calls fail with ERROR_GEN_FAILURE. In this way, you can use the cpszUsername parameter to check whether the correct profile is loaded, or you can use it to check whether your module has just started and should perform the initial UserProfileRead. Note that UserProfileRead(NULL) will prevent the ERROR_GEN_FAILURE return code when cpszUsername==NULL.
Remember that a user may be logged on from several different machines, and that the cached profile is not automatically updated. When the profile is to be changed in permanent storage, it is generally advisable to reread the profile from permanent storage with UserProfileRead, make the change in the cache with userProfileSet, and immediately rewrite the profile with UserProfileWrite; this reduces the chance that another user's changes will be lost.
When successful, the UserProfile APIs return NO_ERROR (0). The following are the error codes returned by the UserProfile APIs:
NERR_BadUsername: bad username argument NERR_InvalidDevice: bad devicename argument ERROR_BAD_NETPATH: bad lanroot argument ERROR_BAD_NET_NAME: bad remotename argument NERR_UseNotFound: the specified device is not listed in the profile ERROR_NOT_ENOUGH_MEMORY: lack of global memory or overfull profile ERROR_GET_FAILURE: username mismatch ERROR_FILE_NOT_FOUND: any file read error ERROR_WRITE_FAULT: any file write error
BUGBUG We must determine correct behavior when no user is logged on. BUGBUG Do we return ERROR_GEN_FAILURE? NO_ERROR? what?
User preferences routines:
These routines read and write sticky values in some section of the local LANMAN.INI. These sticky values are therefore all local to the workstation; this mechanism is not intended for values associated with a user. Unlike the UserProfile routines, these routines do not cache any data.
