pthread_attr_setstacksize(3)

PTHREAD_A...TSTACKSIZE(3)  Linux Programmer's Manual PTHREAD_A...TSTACKSIZE(3)

NAME
       pthread_attr_setstacksize,  pthread_attr_getstacksize  -  set/get stack
       size attribute in thread attributes object

SYNOPSIS
       #include <pthread.h>

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

       Compile and link with -pthread.

DESCRIPTION
       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  ob‐
       ject attr.

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

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

ERRORS
       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.

VERSIONS
       These functions are provided by glibc since version 2.1.

CONFORMING TO
       POSIX.1-2001, POSIX.1-2008.

NOTES
       For details on the default stack size of new threads, see  pthread_cre‐
       ate(3).

       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.

BUGS
       As at glibc 2.8, if the  specified  stacksize  is  not  a  multiple  of
       STACK_ALIGN  (16  bytes on most architectures), it may be rounded down‐
       ward, in violation of POSIX.1, which says that the allocated stack will
       be at least stacksize bytes.

EXAMPLE
       See pthread_create(3).
