Return values are broken up into groups: * * http://msdn2.microsoft.com/en-gb/library/aa489609.aspx * * NT_SUCCESS 0 - 0x3FFFFFFF * NT_INFORMATION 0x40000000 - 0x7FFFFFFF * NT_WARNING 0x80000000 - 0xBFFFFFFF * NT_ERROR 0xC0000000 - 0xFFFFFFFF * * Effectively, we don't care on the severity of the return value from * system(), we just need to know if it was because of exit() or generated * by the system, and it seems values >= 0x100 are system-generated. * See this URL for a list of WIN32 STATUS_* values: * * Wine (URL used in our error messages) - * http://source.winehq.org/source/include/ntstatus.h * Descriptions - http://www.comp.nus.edu.sg/~wuyongzh/my_doc/ntstatus.txt * MS SDK - http://www.nologs.com/ntstatus.html * * It seems the exception lists are in both ntstatus.h and winnt.h, but * ntstatus.h has a more comprehensive list, and it only contains * exception values, rather than winnt, which contains lots of other * things: * * http://www.microsoft.com/msj/0197/exception/exception.aspx * * The ExceptionCode parameter is the number that the operating system * assigned to the exception. You can see a list of various exception codes * in WINNT.H by searching for #defines that start with "STATUS_". For * example, the code for the all-too-familiar STATUS_ACCESS_VIOLATION is * 0xC0000005. A more complete set of exception codes can be found in * NTSTATUS.H from the Windows NT DDK. * * Some day we might want to print descriptions for the most common * exceptions, rather than printing an include file name.
