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.
