semanage_exists - SELinux Management API

Behavior:
              The exists function will return 0 if a matching key is not found, and 1 otherwise.

       Parameters:
              The  handle  is used to track persistent state across semanage calls, and for error reporting. The
              key identifies the object being checked. The result of the test will  be  stored  in  the  address
              pointed  by  response  The  key  is  a  property of the caller, and will not be stored or modified
              internally.

       Requirements:
              This function requires an semanage connection to be established (see semanage_connect(3) )

       In case of failure, -1 is returned, and the semanage error callback is  invoked,  describing  the  error.
       Otherwise  a  non-negative integer is returned (a commit number). The same number will be returned by all
       other read calls to the semanage database until the next commit.
