The following iterate function is supported for any semanage record.
Replace the function and object name as necessary.
extern int ITERATE_FUNCTION (
int (*handler) (
const semanage_OBJECT_t *object,
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).
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.
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.
