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.
