checksimul callback

[Dmitry V. Krivenok]

Hello!
I'm writing my own module.

What is the purpose of checksimul callback?
When is it called?

The prototype of this function is

  static int rlm_myrlm_checksimul(void *instance, REQUEST * request);

hence it should modify something in request.
Likely simul_count field.

What function checks this (or maybe another) field?
How can I set the maximum number of simultaneous sessions?

Thank you beforehand!
