vlc_mta_acquire()

static bool vlc_mta_acquire ( vlc_object_t *  p_parent )

inlinestatic

Ensure an MTA context will be available until vlc_mta_release gets called.

In the background, this will create a thread that does nothing but to keep the MTA refcount greater than 0.

This is usefull in order not to commit a thread to a specific concurrency model. This function is win32 specific.
