83 * For WIN32, there is no wait() call so there are no wait() macros
84 * to interpret the return value of system(). Instead, system()
85 * return values < 0x100 are used for exit() termination, and higher
86 * values are used to indicated non-exit() termination, which is
87 * similar to a unix-style signal exit (think SIGSEGV ==
88 * STATUS_ACCESS_VIOLATION). Return values are broken up into groups:
90 * http://msdn2.microsoft.com/en-gb/library/aa489609.aspx
92 * NT_SUCCESS 0 - 0x3FFFFFFF
93 * NT_INFORMATION 0x40000000 - 0x7FFFFFFF
94 * NT_WARNING 0x80000000 - 0xBFFFFFFF
95 * NT_ERROR 0xC0000000 - 0xFFFFFFFF
97 * Effectively, we don't care on the severity of the return value from
98 * system(), we just need to know if it was because of exit() or generated
99 * by the system, and it seems values >= 0x100 are system-generated.
100 * See this URL for a list of WIN32 STATUS_* values:
102 * Wine (URL used in our error messages) -
103 * http://source.winehq.org/source/include/ntstatus.h
104 * Descriptions - http://www.comp.nus.edu.sg/~wuyongzh/my_doc/ntstatus.txt
105 * MS SDK - http://www.nologs.com/ntstatus.html
107 * It seems the exception lists are in both ntstatus.h and winnt.h, but
108 * ntstatus.h has a more comprehensive list, and it only contains
109 * exception values, rather than winnt, which contains lots of other
112 * http://www.microsoft.com/msj/0197/exception/exception.aspx
114 * The ExceptionCode parameter is the number that the operating system
115 * assigned to the exception. You can see a list of various exception codes
116 * in WINNT.H by searching for #defines that start with "STATUS_". For
117 * example, the code for the all-too-familiar STATUS_ACCESS_VIOLATION is
118 * 0xC0000005. A more complete set of exception codes can be found in
119 * NTSTATUS.H from the Windows NT DDK.
121 * Some day we might want to print descriptions for the most common
122 * exceptions, rather than printing an include file name. We could use
123 * RtlNtStatusToDosError() and pass to FormatMessage(), which can print
124 * the text of error values, but MinGW does not support
125 * RtlNtStatusToDosError().
