Function Description:
This function reads all or part of information from a SCP/SAP/SMP profile
depending on the ProfileType, into the InfoBuffer. ProfileType is saved in
the ppInfoBuffer's Type field.
A handle to the profile (Jet database) is passed into the routine every
time this routine is called. Area specifies one or more pre-defined security
areas to get information. One area's information may be saved in multiple
sections in the profile.
The memory related to the area(s) will be reset/freed before loading
information from the profile. If the return code is SCESTATUS_SUCCESS, then
the output InfoBuffer contains the requested information. Otherwise,
InfoBuffer contains nothing for the area(s) specified.
Arguments:
hProfile - The handle to the profile to read from.
ProfileType - value to indicate engine type.
SCE_ENGINE_SCP
SCE_ENGINE_SAP
SCE_ENGINE_SMP
Area - area(s) for which to get information from
AREA_SECURITY_POLICY
AREA_PRIVILEGES
AREA_GROUP_MEMBERSHIP
AREA_REGISTRY_SECURITY
AREA_SYSTEM_SERVICE
AREA_FILE_SECURITY
ppInfoBuffer - The address of SCP/SAP/SMP buffers. If it is NULL, a buffer
will be created which must be freed by LocalFree. The
output is the information requested if successful, or
nothing if fail.
Errlog - A buffer to hold all error codes/text encountered when
parsing the INF file. If Errlog is NULL, no further error
information is returned except the return DWORD
Return Value:
SCESTATUS_SUCCESS
SCESTATUS_PROFILE_NOT_FOUND
SCESTATUS_NOT_ENOUGH_RESOURCE
SCESTATUS_INVALID_PARAMETER
SCESTATUS_BAD_FORMAT
SCESTATUS_INVALID_DATA

Function Description:
This routine get a dynamic section's information for a security area.
Dynamic sections are those created dynamically, based on other sections'
related information. Dynamic sections in a profile include User Security
Profiles for SCP and User Settings for SAP/SMP. Name contains the section's
identifier, either the section's name, or a partial name (e.g., a user
name) for the section. The output must be casted to different structure,
depending on the ProfileType and Area.
The output buffer contains one instance of the requested information,
e.g., one user security profile or one user's setting. To get all dynamic
sections, this routine must be called repeatly. The output buffer must
be freed by LocalFree after its use.
Arguments:
hProfile - The handle of the profile
ProfileType - The type of the profile to read
Name - The dynamic section's identifier
ppInfo - Output buffer (PSCE_USER_PROFILE or PSCE_USER_SETTING)
Errlog - The error log buffer

Routine Description:
This routine is used for Registry and File Security ONLY.
This routine takes a object prefix ( e.g., a parent node<64>s full path name)
and outputs all files and sub directories under the object, or the immediate
children under the object, based on Option. When all files and sub
directories are outputted, the output information is in a n-tree structure
(SCE_OBJECT_TREE). If only the immediate children are outputted, the
output information is in a list structure (SCE_OBJECT_CHILDREN). The output buffer
must be freed by LocalFree after its use.
Arguments:
hProfile - The handle to the profile
ProifleType - The type of the profile to read
Area - The security area to read info
AREA_REGISTRY_SECURITY
AREA_FILE_SECURITY
ObjectPrefix- The parent node<64>s full path name (e.g., c:\winnt)
Option - The option for output information. Valid values are
SCE_ALL_CHILDREN
SCE_IMMEDIATE_CHILDREN
Buffer - The output buffer.
Errlog - The error log buffer.
Return Value:
SCESTATUS_SUCCESS
SCESTATUS_PROFILE_NOT_FOUND
SCESTATUS_NOT_ENOUGH_RESOURCE
SCESTATUS_INVALID_PARAMETER
SCESTATUS_BAD_FORMAT
