Re: increasing stack size

i have a program that has a task on a pthread that is running out of stack size (crashes in memcpy) i cant get pb to allow me to set the stack_size parameter to the linker. tried

Xlinker stack_size xxxx, W1, stack=xxx some other variants of this on the link options other macho link flags line.

can anyone point me at how to increase the stack available to a carbon app?

thanks jim

Are you actually using pthreads? Then you must be using mach-o, and this will work (semi-pseudo code, no error checking).

pthread_attr_t theAttributes;
pthread_attr_init(&theAttributes);

if (stackSize > PTHREAD_STACK_MIN)
{
size_t currStackSize;
pthread_attr_getstacksize(&theAttributes, &currStackSize);
if (stackSize != currStackSize)
{
currStackSize = stackSize;
pthread_attr_setstacksize(&theAttributes, currStackSize);
}

pthread_create(&theThread, &theAttributes,
startRoutine, startRoutineData);
}

If you're using the MPLibrary, then I think there is a call to set the stack size for a thread; see CarbonCore/Multiprocessing.h.
