Thread attributes are used to specify parameters to
pthread_create
().
One attribute object can be used in multiple calls to
pthread_create
(), with or without modifications
between calls.
The functions
pthread_attr_setstacksize
()
and
pthread_attr_getstacksize
(),
respectively, set and get the size of the stack that is to be created for
the new thread. The stack size attribute is set within the
attr argument, which can subsequently be used as an
argument to pthread_create
().
If successful, these functions return 0. Otherwise, an error
number is returned to indicate the error.
pthread_attr_getstacksize
() returns the stacksize
attribute value in stacksize if successful.
pthread_attr_getstacksize
() will fail
if:
EINVAL
]pthread_attr_setstacksize
() will fail
if:
pthread_create(3), pthread_attr_init(3), pthread_attr_setstackaddr(3)
pthread_attr_setstacksize
(),
pthread_attr_getstacksize
() conform to
