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.
