Parameters
For the definitions of the return_code, reason_code, exit_data_length, and exit_data
parameters, see “Parameters Common to All Verbs” on page 1-11.
rule_array_count
The rule_array_count parameter is a pointer to an integer variable containing
the number of elements in the rule_array variable. The value must be zero for
this verb.
rule_array
The rule_array parameter is a pointer to a string variable containing an array of
keywords. The keywords are eight bytes in length, and must be left-justified
and padded on the right with space characters. The rule_array parameter is
not presently used by this verb, but must be specified.
source_key_identifier_length
The source_key_identifier_length parameter is a pointer to an integer variable
containing the number of bytes of data in the source_key_identifier variable.
The maximum size that should be specified is 2500 bytes.
source_key_identifier
