Using Defined Constants To Set Bits

Certain structures require that you use defined constants to set bits to request specific items like attributes, actions, and concurrency control. You request an item by setting a bit to ON (1). Refer to the following table for a list of defined constants and their corresponding structures.

Defined Constants	Corresponding Structures
FT_FA_XXX	Ft_file_actions
FT_AG_XXX	Ft_attribute_ groups
FT_AN_XXX	Ft_attribute_names
FT_AC_XXX	Ft_access_control_element
FT_PA_XXX	Ft_permitted_actions
FT_FT_XXX	Ft_functional_units
FT_PM_XXX	Ft_processing_mode
FT_SC_XXX	Ft_service_class

Use the defined constant to set the bits to either ON (1) or OFF (0). Setting bits other than those listed results in an error.
If needed, set the bit by first defining a variable. Use the appropriate defined constant to set the bit you want.

EXAMPLE

This example sets the filename and contents_type attributes in the variable called attribute_names.

Ft_attribute_names attribute_names;

attribute_names = (FT_AN_FILENAME | FT_AN_CONTENT_TYPE);
