I am writing a multi-threaded program under Unix Solaris. The program
creates multiple threads ( each which forks a child process) using
thr_create(). The parent thread waits for the child thread (using thr_join)
before creating any more threads. But I am getting a
free_stack: munmap Invalid argument error when new threads are created.
Is the stack_size argument in thr_create() to small or is this a memory
problem within the program ?

Thanks in advance,

Ja Uhm

It depends...What does your call to thr_create() look like ? Are
supplying values for the stack base and stack size or are you
specifying thr_min_stack ? Need more info. Also consider reading and
posting to comp.programming.threads.
