NAME

       semanage_exists - SELinux Management API

SYNOPSIS

       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

       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

       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.
