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.
