pthread_stackseg_np(pthread_t

DESCRIPTION
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.
RETURN VALUES
If successful, the pthread_stackseg_np()
function will return 0. Otherwise an error number will be returned to
indicate the error.
ERRORS
The pthread_stackseg_np() function will
fail if:
- [
EAGAIN] - Stack information for the given thread is not currently available. There is no guarantee that the given thread's stack information will ever become available.

STANDARDS
pthread_stackseg_np() is a non-portable
extension to IEEE Std 1003.1-2001
(“POSIX.1”).
