unsigned int dbus_uint32_t
A 32-bit unsigned integer on all platforms.
An atomic integer safe to increment or decrement from multiple threads.
Definition: dbus-sysdeps.h:339
dbus_uint32_t changed_stamp
Incremented when iterators are invalidated.
#define DBUS_BEGIN_DECLS
Macro used prior to declaring functions in the D-Bus header files.
DBusList * messages
Complete messages.
DBUS_PRIVATE_EXPORT dbus_bool_t _dbus_message_iter_get_args_valist(DBusMessageIter *iter, DBusError *error, int first_arg_type, va_list var_args)
Implementation of the varargs arg-getting functions.
Definition: dbus-message.c:838
DBusString body
Body network data.

#define CHANGED_STAMP_BITS
How many bits are in the changed_stamp used to validate iterators.
Object representing an exception.
Definition: dbus-errors.h:50
unsigned int in_cache
Has been "freed" since it's in the cache (this is a debug feature)
Data structure that stores the actual user data set at a given slot.
Definition: dbus-dataslot.h:71
long max_message_unix_fds
Maximum unix fds in a message.
unsigned int corrupted
We got broken data, and are no longer working.

DBusValidity corruption_reason
why we were corrupted
Implementation details of DBusMessageLoader.
DBusDataSlotList slot_list
