Ways to insert unique ID into a logging function

[Paul McKenzie]

So, I was wondering, is there any way to make compiler insert a unique ID for me?

Have you considered calling the API functions that generate GUID's? That is what is usually done if a unique ID for any purpose needs to be generated.

A GUID is virtually guaranteed to be unique (virtually meaning that the chance of generating duplicate GUID's is astronomically small).
