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.

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.
