PTHREAD_STACKSEG_NP(3) BSD Programmer's Manual PTHREAD_STACKSEG_NP(3)
pthread_stackseg_np - return stack size and location
#include <sys/signal.h>
#include <pthread_np.h>
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. Other-
wise an error number will be returned to indicate the error.
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.
sigaltstack(2), pthreads(3)
pthread_stackseg_np() is a non-portable extension to IEEE Std 1003.1-2001
("POSIX").
