| * ------------------------------------------------------ |
| * 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 |
