Invokes a function in such a way that context is owned during the
invocation of function.
If context is NULL then the global default main context — as
returned by g_main_context_default() — is used.
If context is owned by the current thread, function is called
directly. Otherwise, if context is the thread-default main context
of the current thread and g_main_context_acquire() succeeds, then
function is called and g_main_context_release() is called
afterwards.
In any other case, an idle source is created to call function and
that source is attached to context (presumably to be run in another
thread). The idle source is attached with G_PRIORITY_DEFAULT
priority. If you want a different priority, use
g_main_context_invoke_full().
Note that, as with normal idle functions, function should probably
return FALSE. If it returns TRUE, it will be continuously run in a
loop (and may prevent this call from returning).
