Using Defined Constants To Set Bits
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.
• 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);
