43 * ------------------------------------------------------
44 * DOCPUBLIC
45 * This function specifies the size of the stack on
46 * which threads created with 'attr' will run.
47 *
48 * PARAMETERS
49 * attr
50 * pointer to an instance of pthread_attr_t
51 *
52 * stacksize
53 * stack size, in bytes.
54 *
55 *
56 * DESCRIPTION
57 * This function specifies the size of the stack on
58 * which threads created with 'attr' will run.
59 *
60 * NOTES:
61 * 1) Function supported only if this macro is
62 * defined:
63 *
64 * _POSIX_THREAD_ATTR_STACKSIZE
65 *
66 * 2) Find the default first (using
67 * pthread_attr_getstacksize), then increase
68 * by multiplying.
69 *
70 * 3) Only use if thread needs more than the
71 * default.
72 *
73 * RESULTS
74 * 0 successfully set stack size,
75 * EINVAL 'attr' is invalid or stacksize too
76 * small or too big.
77 * ENOSYS function not supported
