This object provides an abstraction for creating threads. The default implementation uses a regular GThreadPool to start tasks.
Subclasses can be made to create custom threads.
void
(*GstTaskPoolFunction) (void *user_data);
Task function, see gst_task_pool_push().
GstTaskPool *
gst_task_pool_new (void);
Create a new default task pool. The default task pool will use a regular GThreadPool for threads.
void gst_task_pool_prepare (GstTaskPool *pool,GError **error);
Prepare the taskpool for accepting gst_task_pool_push() operations.
MT safe.
gpointer gst_task_pool_push (GstTaskPool *pool,GstTaskPoolFunction func,gpointer user_data,GError **error);
Start the execution of a new thread from pool
.

func |
the function to call. |

user_data |
data to pass to |
[closure] |
error |
return location for an error |
a pointer that should be used
for the gst_task_pool_join function. This pointer can be NULL, you
must check error
to detect errors.

void gst_task_pool_join (GstTaskPool *pool,gpointer id);
Join a task and/or return it to the pool. id
is the id obtained from
gst_task_pool_push().
void
gst_task_pool_cleanup (GstTaskPool *pool);
Wait for all tasks to be stopped. This is mainly used internally to ensure proper cleanup of internal data structures in test suites.
MT safe.
