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.
