key_verify/3—validate and retrieve fields from a license  key

The syntax for key_verify/3 is as follows:

key_verify($KEY,$FIELDS,$VALID)

key_verify/3 arguments 

Argument

Mode

Type

Description

$KEY

Input

STRING

Specifies the license key

$FIELDS

Output

LIST_OF STRING

List of fields from key

$VALID

Output

INTEGER

Key validity (0=invalid, 1=valid)

Use the key_verify/3 to determine the validity of license key $KEY in $VALID, and to retrieve fields from the key and return them in $FIELDS.

A license key is a string containing licensing information, as provided by BMC.

The application is responsible to determine the exact number of fields that are expected in the key. The $FIELDS argument has to be specified as a list of as many variables as the number of fields.

If the key is invalid, or if the number of fields is not exact, $VALID will be set to 0. Otherwise, it will be set to 1.

key_verify/3 example

key_verify($KEY,[$FLD1,$FLD2],$VALID);
$LICDATA.key_validity = $VALID;
