PTHREAD_ATTR_SETSTACKADDR(3)        Linux Programmer's Manual        PTHREAD_ATTR_SETSTACKADDR(3)



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

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

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

VERSIONS
       These functions are provided by glibc since version 2.1.

ATTRIBUTES
   Multithreading (see pthreads(7))
       The pthread_attr_setstackaddr() and pthread_attr_getstackaddr() functions are thread-safe.

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

NOTES
       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 architec‐
       tures 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 con‐
       trast,  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).
