size attribute in thread attributes object

       #include <pthread.h>

       int pthread_attr_setstacksize(pthread_attr_t *attr, size_t stacksize);
       int pthread_attr_getstacksize(pthread_attr_t *attr, size_t *stacksize);

       Compile and link with -pthread.

       The pthread_attr_setstacksize() function sets the stack size  attribute
       of the thread attributes object referred to by attr to the value speci-
       fied in stacksize.

       The stack size attribute determines the minimum size  (in  bytes)  that
       will  be  allocated  for  threads  created  using the thread attributes
       object attr.

       The  pthread_attr_getstacksize()  function  returns  the   stack   size
       attribute  of  the  thread attributes object referred to by attr in the
       buffer pointed to by stacksize.

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

       pthread_attr_setstacksize() can fail with the following error:

       EINVAL The stack size is less than PTHREAD_STACK_MIN (16384) bytes.

       On  some  systems,  pthread_attr_setstacksize() can fail with the error
       EINVAL if stacksize is not a multiple of the system page size.

       These functions are provided by glibc since version 2.1.


       See pthread_create(3).

       For details on the default stack size of new threads, see  pthread_cre-

       A  thread's  stack  size is fixed at the time of thread creation.  Only
       the main thread can dynamically grow its stack.

       The pthread_attr_setstack(3) function allows an application to set both
       the size and location of a caller-allocated stack that is to be used by
       a thread.
