semanage_iterate(3) Libsemanage API documentation semanage_iterate(3)
semanage_iterate - SELinux Management API
The following iterate function is supported for any semanage record.
Replace the function and object name as necessary.
extern int ITERATE_FUNCTION (
semanage_handle_t *handle,
int (*handler) (
const semanage_OBJECT_t *object,
void *varg),
void *handler_arg);
Behavior:
The iterate function will execute the specified handler over
all objects in the selected location. An arbitrary argument
can be passed into the handler function along with each
object.
The object passed in is property of the libsemanage library,
and may not be modified or preserved - use
semanage_OBJECT_clone if that is necessary.
The handler code may not invoke any semanage write requests
for the same object type (i.e. modifying the underlying store
is not allowed). The iterate function is reentrant only while
inside a transaction (see semanage_begin_transaction ). It is
not safe to execute other semanage read or write requests
within iterate if not inside a transaction. The handler may
return -1 to signal error exit, 0 to signal continue, and 1 to
signal successful exit early (the iterate function will stop
accordingly).
Parameters:
The handle is used to track persistent state across semanage
calls, and for error reporting. The handler is the function to
execute, with handler_arg as its second parameter, and each
object as its first parameter.
Requirements:
This function requires an semanage connection to be
established (see semanage_connect(3) )
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 semanage object read calls until the next commit.
