Functions and macros related to threads and thread locks.

Creates a new condition variable using the function supplied to dbus_threads_init(), or creates a no-op condition variable if threads are not initialized. May return NULL even if threads are initialized, indicating out-of-memory.

Atomically unlocks the mutex and waits for the conditions variable to be signalled. Locks the mutex again before returning. Does nothing if passed a NULL pointer. Definition at line 145 of file dbus-threads.c. References DBusThreadFunctions::condvar_wait. |

Locks a mutex. Does nothing if passed a NULL pointer. Locks are not recursive.

Unlocks a mutex. Does nothing if passed a NULL pointer.

|
Initializes threads. If this function is not called, the D-BUS library will not lock any data structures. If it is called, D-BUS will do locking, at some cost in efficiency. Note that this function must be called BEFORE using any other D-BUS functions. This function may be called more than once, as long as you pass in the same functions each time. If it's called multiple times with different functions, then a warning is printed, because someone is confused.
