|
* This function specifies the size of the stack on

|

*
|
||
|
|
* PARAMETERS
|
||
|
|
* attr
|
||
|
|
* pointer to an instance of pthread_attr_t
|
||
|
|
*
|
||
|

|
|
* 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

||
