The 'GI.GLib.Structs.ThreadPool.ThreadPool' struct represents a thread pool. It has three
public read-only members, but the underlying struct is bigger,
so you must not copy this struct.

Frees all resources allocated for /@pool@/.

If /@immediate@/ is 'True', no new task is processed for /@pool@/.
Otherwise /@pool@/ is not freed before the last task is processed.
Note however, that no thread of this pool is interrupted while
processing a task. Instead at least all still running threads
can finish their tasks before the /@pool@/ is freed.

If /@wait_@/ is 'True', the functions does not return before all
tasks to be processed (dependent on /@immediate@/, whether all
or only the currently running) are ready.
Otherwise the function returns immediately.

After calling this function /@pool@/ must not be used anymore.

Sets the maximal allowed number of threads for /@pool@/.
A value of -1 means that the maximal number of threads
is unlimited. If /@pool@/ is an exclusive thread pool, setting
the maximal number of threads to -1 is not allowed.

Setting /@maxThreads@/ to 0 means stopping all work for /@pool@/.
It is effectively frozen until /@maxThreads@/ is set to a non-zero
value again.

A thread is never terminated while calling /@func@/, as supplied by
@/g_thread_pool_new()/@. Instead the maximal number of threads only
has effect for the allocation of new threads in 'GI.GLib.Structs.ThreadPool.threadPoolPush'.
A new thread is allocated, whenever the number of currently
running threads in /@pool@/ is smaller than the maximal number.

/@error@/ can be 'Nothing' to ignore errors, or non-'Nothing' to report
errors. An error can only occur when a new thread couldn\'t be
created.
