+ * ------------------------------------------------------
+ * DOCPUBLIC
+ * This function specifies the size of the stack on
+ * which threads created with 'attr' will run.
+ *
+ * PARAMETERS
+ * attr
+ * pointer to an instance of pthread_attr_t
+ *
+ * stacksize
+ * stack size, in bytes.
+ *
+ *
+ * DESCRIPTION
+ * This function specifies the size of the stack on
+ * which threads created with 'attr' will run.
+ *
+ * NOTES:
+ * 1) Function supported only if this macro is
+ * defined:
+ *
+ * _POSIX_THREAD_ATTR_STACKSIZE
+ *
+ * 2) Find the default first (using
+ * pthread_attr_getstacksize), then increase
+ * by multiplying.
+ *
+ * 3) Only use if thread needs more than the
+ * default.
+ *
+ * RESULTS
+ * 0 successfully set stack size,
+ * EINVAL 'attr' is invalid or stacksize too
+ * small or too big.
+ * ENOSYS function not supported
+ *
+ * ------------------------------------------------------
