Why does lseek return 0?

Otherwise, a value of -1 is returned and errno is set to indicate the error. Trouble is, not even ...
Two versions of mysql on one Mac server, need to get data from one to other
My sysadmin patches my Mac server, and suddenly MySQL is pointing at a version 5 install. Prior to this, it was pointing to a version 4 install. My data is stranded in the version 4.

EADDRNOTAVAIL when binding 127.0.0.1 on localhost?
I'm getting errno==49 (EADDRNOTAVAIL) when trying to UDP-bind() to 127.0.0.1:47346 running Mac OS X on a G5 (big endian PowerPC). Is there something preventing me from doing so? I've tried other addresses and ports (192.168.1.2 and port 47346) but with no success. Here's a gdb printout of my sockaddr_in: $1 = { sin_len = 0 '\0', s...
STLport crash (race condition, Darwin only?)
When I run STLport on Darwin I get a strange crash. (Haven't seen it anywhere else than on Mac, but exactly same thing crash on both i686 and PowerPC.)

OSX/Darwin unresolved symbols when linking functions from <math.h>
I'm in the process of porting a large'ish (~1M LOC) project from a Window/Visual Studio environment to other platforms, the first of which happens to be Mac OS X.

Does operator new allocate on THREAD heap?
My problem seems to be this: heap data allocated by one thread (that later dies) seems to die as well. As so: Thread X: starts Thread Y: starts Thread X: ptr = new some bytes Thread X: dies Thread Y: tries to use ptr - and crashes! So far, I've only seen this problem on Darwin (Mac OS 10.5 and 10.6), but haven't tried more other plat...

Handling mach exceptions in 64bit OS X application
I have been able to register my own mach port to capture mach exceptions in my applications and it works beautifully when I target 32 bit. However when I target 64 bit, my exception handler catch_exception_raise() gets called but the array of exception codes that is passed to the handler are 32 bits wide. This is expected in a 32 bit bui...
Using *Darwin as a test bed for Mac OSX applications
Since Mac virtualization is technically illegal on anything but a Mac computer, is it possible to use one of the Darwin distros as a platform to test applications meant for Mac OSX? From the little I've read, it seems *Darwin and MacOSX have a very tight relationship, but I haven't really found any information on the internet about usi...
building odcctools in a 64-bit OS
The odcctools package provides binutils for the Darwin OS. -- this allows you to cross compile to Darwin and OSX for example. However, odcctools does not seem to build properly on 64-bit OSes: ./../expr.c: In function ‘expression’: ./../expr.c:311: error: ‘union <anonymous>’ has no member named ‘n_name’ Or, if you set CFLAGS to -m32, ...
