PTHREAD_ATTR_SETSTACKADDR(3Linux Programmer's ManuPTHREAD_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_set-
     stack(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.

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 architectures with a stack that grows down-
     ward,  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_set-
     stack(3)  and pthread_attr_getstack(3), is always a pointer to the low-
     est address in the allocated stack area  (and  the  stacksize  argument
     specifies the range of the stack).
