    PrintAttributesByType()

    Searches for and prints all attributeSchema objects that contain all of 
    the specified attribute type flags.

    Parameters:

    pSchemaNC - IDirectorySearch pointer to schema naming context.

    dwAttributeType - Bit flags to search for in systemFlags. These are 
        values such as ADS_SYSTEMFLAG_ATTR_IS_CONSTRUCTED.

    bIsExactMatch - TRUE to find attributes that have systemFlags exactly 
        matching dwAttributeType. FALSE to find attributes that have the 
        dwAttributeType bit set, and possibly others.
