| I have run into a rather strange problem I can't get my head around.
I have a program that works correctly when run from Xcode or Finder, but if I try to debug it a certain section of code fails every time. I am simply opening a CD using opendev() than calling ioctl() to read the disc's TOC:
_fd = opendev((char *)[[self deviceName] fileSystemRepresentation], O_RDONLY | O_NONBLOCK, 0, NULL);
if(-1 == ioctl([self fileDescriptor], DKIOCCDREADTOC, &cd_read_toc)) {
I've omitted the error handling code, but I do checking. opendev() works every time, but as I mentioned, ioctl() fails from the debugger. Any ideas why?
