Синопсис (Synopsis)
The following exists function is supported for any semanage
record.

extern int EXISTS_FUNCTION (
semanage_handle_t *handle,
const semanage_OBJECT_key_t *key,
semanage_OBJECT_t **response);
Описание (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) )
Возвращаемое значение (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.
