RTErrConvertFromErrno.cpp@ 77110

Last change on this file since 77110 was 77110, checked in by vboxsync, 6 years ago
RTErrConvertFromErrno(): Convert the uNativeCode parameter from unsigned to int. errno is specified to be of type int and while it should only ever contain positive values RTErrConvertFromErrno() is also used inside the various kernel drivers where errno does not exist and the return code might be negative as well. The example here is ERESTART (-1) on FreeBSD causing a compile error with clang and this fix is cleaner IMO instead of casting ERSTART to unsigned.
