C Any one know how to get the procdesc of the current process?

[Ferocious1881]

I am writing a toy program over capsicum, which will send its procdesc as authentication over Unix domain sockets, but have not found documentation of how to get the procdesc of the current process.

pdfork(2)() says:

Process descriptors are special file descriptors that represent processes, and are created using pdfork(),

So, it seems that there is no procdesc assigned to the current process if it is not invoked by pdfork(2).

Yes. Technically, it's "just" a file descriptor (an integer identifier), so I guess there's a misunderstanding of its purpose. It just allows an alternative way to refer to your own child processes, for example attaching capsicum capabilities to it. There's no point in trying to get such an fd "for yourself", and it's not meant for any kind of authentication.
