Re: ErrorException thrown when errno is modified ?

Does this affect the posix calls ? It just means the Phobos functions that use these functions (like std.file or std.socket) might throw the exception, not the C functions themselves.

From what I saw in the code, it doesn't seam the case. Just making sure I'm correct. ErrnoException is the exception thrown by errnoEnforce, which is a convenient function for checking system calls. D links to the same Posix functions that C does; their behavior is exactly the same (ie they don't throw).

From what I saw in the code, it doesn't seam the case. Just making sure I'm correct. I think the description for ErrnoException is a bit misleading. I'm fairly certain that there is no code running that watches errno and throws an ErrnoException whenever it gets set. Rather, code that calls C functions which set errno can/should use ErrnoException and the errnoEnforce helper function to make a nice Exception from an errno value.
