Hi,

I am using a Radio Layer Interface (RIL) Native API in Windows Mobile application. In this API, the return values / results of most functions are not returned immediately but are passed through a callback function which is passed to the RIL API.

Some usage examples are found at XDA Develompent Tools and Google Gears Geolocation API.

My question is, in these two examples, a mutex is used to guard the data instead of other synchronization objects.

Now, will Critical Section do fine here in the use cases described by both examples? Which thread or process will actually call the callback functions?
