int
pthread_stackseg_np
(pthread_t
thread, stack_t
*sinfo);
The
pthread_stackseg_np
()
function returns information about the given thread's stack. A
stack_t is the same as a struct
sigaltstack (see
sigaltstack(2)) except the
ss_sp variable points to the top of the stack instead
of the base.
If successful, the pthread_stackseg_np
()
function will return 0. Otherwise an error number will be returned to
indicate the error.
The pthread_stackseg_np
() function will
fail if:
EAGAIN
]pthread_stackseg_np
() is a non-portable
extension to IEEE Std 1003.1-2001
(“POSIX.1”).
