How to get the calling application's PID in policy opcode

Hello

How can I get the PID of the application which called billing in billing policy opcode (eg PCM_OP_BILL_POL_POST_BILLING)?

Or more generally: how can I get the PID of the application which called an opcode?

Is it somewhere in the context?

The PID is in the log so it should be possible to get it.

It would be the red text in sample log line:

Best regards,
