Missing piece of system information in OTP.
This is small library that allows users to fetch more information about the current process from the OS. ERTS support only one information - process ID (that is strangely returned as a charlist).
This library exposes more info about process:
- process ID (as integer)
- priority
- effective/real group/user ID (on Unixes)
- user name (on Windows)
In addition to that, there is small helper function that also return C type sizes.
