NAME         top

       semanage_exists - SELinux Management API

SYNOPSIS         top

       The following exists function is supported for any semanage record.
       Replace the function and object name as necessary.

       extern int EXISTS_FUNCTION (
            semanage_handle_t *handle,
            const semanage_OBJECT_key_t *key,
            semanage_OBJECT_t **response);

DESCRIPTION         top

       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) )

RETURN VALUE         top

       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.
