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.
