pthread_attr_setstackaddr, pthread_attr_getstackaddr − set/get stack address attribute in thread attributes object #include<pthread.h> , void *int pthread_attr_setstackaddr(pthread_attr_t *attr , void **int pthread_attr_getstackaddr(const pthread_attr_t *attr Compile and link with −pthread. These functions are obsolete: usedonot Use and instead. The function sets the stack address attribute of the thread attributes object referred to by attr to the value specified in This attribute specifies the location of the stack that should be used by a thread that is created using the thread attributes object stackaddr should point to a buffer of at least PTHREAD_STACK_MIN bytes that was allocated by the caller. The pages of the allocated buffer should be both readable and writable. The function returns the stack address attribute of the thread attributes object referred to by attr in the buffer pointed to by On success, these functions return 0; on error, they return a nonzero error number. No errors are defined (but applications should nevertheless handle a possible error return). These functions are provided by glibc since version 2.1.

POSIX.1‐2008 removes the specification of these functions. useDonot They cannot be portably used, since they provide no way of specifying the direction of growth or the range of the stack. For example, on architectures with a stack that grows downward, stackaddr specifies the next address past the highest address of the allocated stack area. However, ‐2‐ on architectures with a stack that grows upward, stackaddr specifies the lowest address in the allocated stack area. By contrast, the stackaddr used by and is always a pointer to the lowest address in the allocated stack area (and the stacksize argument specifies the range of the stack).
