release

Releases ownership of a context previously acquired by this thread with [method@GLib.

MainContext.acquire].

If the context was acquired multiple times, the ownership will be released only when [method@GLib.MainContext.release] is called as many times as it was acquired.

You must have successfully acquired the context with [method@GLib.MainContext.acquire] before you may call this function.

Parameters:

this	a main context (if `NULL`, the global-default main context will be used)
