/*
Routine Description:

    Query information for the service in the configuration/analysis database
    which contains the modified configuration and last analysis information.

    One enumeration returns maximum SCESVC_ENUMERATION_MAX lines (key/value)
    matching the lpPrefix for the service. If lpPrefix is NULL, all information
    for the service is enumerated. If there is more information, psceEnumHandle
    must be used to get next set of keys/values, until *ppvInfo is NULL or Count is 0.

    When bExact is set and lpPrefix is not NULL, exact match on the lpPrefix is
    searched and only one line is returned.

    The output buffer must be freed by SceSvcFree

Arguments:

    sceHandle   - the opaque handle obtained from SCE

    sceType     - the information type to query

    lpPrefix    - the optional key name prefix for the query

    bExact      - TRUE = exact match on key

    ppvInfo     - the output buffer

    psceEnumHandle  - the output enumeration handle for next enumeartion

Return Value:

    SCE status for this operation

Routine Description:

    Save information of a service into security manager internal database. It's up

    Type indicates the type of internal database: CONFIGURATION or ANALYSIS.

Arguments:

    sceHandle   - the opaque handle obtained from SCE

    sceType     - the service information type to set

    lpPrefix    - the key prefix to overwrite

    bExact      - TRUE = only overwrite if there is exact match, insert if no match
