July 22, 2004 Phobos SysError... | ||||
---|---|---|---|---|
| ||||
Attachments: | I just noticed the undocumented? SysError class in phobos. It appears to be for getting the OS error message associated with an error code.
It is currently a switch statement with some errno constants and constant strings.
I think it should be updated to call FormatMessage on windows and strerror on *NIX. Attached is my attempt at it, if it meets aproval pls consider it for inclusion in Phobos.
Regan.

Posted in reply to Regan Heath | I forgot to mention, the Windows functions I needed (FormatMessageA and LocalFree) are not declared in std.c.windows.windows, or aywhere else I could find. Is this because they are defined in winbase.h and no-one has done a D stub for that yet? I have declared them in the attached syserror.d but they should be moved. The attached file may not work on *NIX it may require something like extern (C) char *strerror(int errnum); I'm not sure.

Posted in reply to Regan Heath Attachments: | <g> I always forget to polish my code.. this version has a few fixes, like the removal of the newline from the error string, and the addition of the extern (C) char *strerror(int) etc. Regan On Fri, 23 Jul 2004 00:40:53 +1200, Regan Heath <regan@netwin.co.nz> wrote: > I forgot to mention, the Windows functions I needed (FormatMessageA and LocalFree) are not declared in std.c.windows.windows, or aywhere else I could find. > > Is this because they are defined in winbase.h and no-one has done a D stub for that yet? > > I have declared them in the attached syserror.d but they should be moved. > > The attached file may not work on *NIX it may require something like > extern (C) char *strerror(int errnum); > I'm not sure. > > Regan > > On Fri, 23 Jul 2004 00:33:48 +1200, Regan Heath <regan@netwin.co.nz> wrote: >> I just noticed the undocumented?

They're included with WindowsException (with various useful techniques for loading string messages from different modules), which Walter's been hanging onto for several months, but is still not in Phobos. I'm still waiting ... sigh ... > > Is this because they are defined in winbase.h and no-one has done a D stub for that yet? > > I have declared them in the attached syserror.d but they should be moved. > > The attached file may not work on *NIX it may require something like > extern (C) char *strerror(int errnum); > I'm not sure. > > Regan > > On Fri, 23 Jul 2004 00:33:48 +1200, Regan Heath <regan@netwin.co.nz> wrote: > > I just noticed the undocumented?
