pthread_attr_getstackaddr(3) — Linux manual page



NAME         top

       pthread_attr_setstackaddr,  pthread_attr_getstackaddr - set/get stack
       address attribute in thread attributes object

SYNOPSIS         top

       #include <pthread.h>

       int pthread_attr_setstackaddr(pthread_attr_t *attr, void *stackaddr);
       int pthread_attr_getstackaddr(const pthread_attr_t *attr, void **stackaddr);

       Compile and link with -pthread.

DESCRIPTION         top

       These functions are obsolete: do not use them.  Use
       pthread_attr_setstack(3) and pthread_attr_getstack(3) instead.

       The pthread_attr_setstackaddr() function sets the stack address
       attribute of the thread attributes object referred to by attr to the
       value specified in stackaddr.  This attribute specifies the location
       of the stack that should be used by a thread that is created using
       the thread attributes object attr.

       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 pthread_attr_getstackaddr() function returns the stack address
       attribute of the thread attributes object referred to by attr in the
       buffer pointed to by stackaddr.

RETURN VALUE         top

       On success, these functions return 0; on error, they return a nonzero
       error number.

ERRORS         top

       No errors are defined (but applications should nevertheless handle a
       possible error return).

VERSIONS         top

       These functions are provided by glibc since version 2.1.

CONFORMING TO         top

       POSIX.1-2001 specifies these functions but marks them as obsolete.
       POSIX.1-2008 removes the specification of these functions.

NOTES         top

       Do not use these functions!  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, on architectures with
       a stack that grows upward, stackaddr specifies the lowest address in
       the allocated stack area.  By contrast, the stackaddr used by
       pthread_attr_setstack(3) and pthread_attr_getstack(3), is always a
       pointer to the lowest address in the allocated stack area (and the
       stacksize argument specifies the range of the stack).
