std: Add an unstable method Child::id #25495
Conversation
This commits adds a method to the `std::process` module to get the process identifier of the child as a `u32`. On Windows the underlying identifier is already a `u32`, and on Unix the type is typically defined as `c_int` (`i32` for almost all our supported platforms), but the actually pid is normally a small positive number. Eventually we may add functions to load information about a process based on its identifier or the ability to terminate a process based on its identifier, but for now this function should enable this sort of functionality to exist outside the standard library.
