49 * This function determines the size of the stack on
50 * which threads created with 'attr' will run.
51 *
52 * PARAMETERS
53 * attr
54 * pointer to an instance of pthread_attr_t
55 *
56 * stacksize
57 * pointer to size_t into which is returned the
58 * stack size, in bytes.

61 * DESCRIPTION
62 * This function determines the size of the stack on
63 * which threads created with 'attr' will run.
64 *
65 * NOTES:
66 * 1) Function supported only if this macro is
67 * defined:
68 *
69 * _POSIX_THREAD_ATTR_STACKSIZE
70 *
71 * 2) Use on newly created attributes object to
72 * find the default stack size.
73 *
74 * RESULTS
75 * 0 successfully retrieved stack size,
76 * EINVAL 'attr' is invalid
77 * ENOSYS function not supported
