19.5.1 General [syserr.general]
Subclause [syserr] describes components that the standard library and C++ programs may use to report error conditions originating from the operating system or other low-level application program interfaces.
Components described in [syserr] do not change the value oferrno ([errno]).
Recommended practice: Implementations should leave the error states provided by other libraries unchanged.
