pthread_attr_setstacksize(3c)

Standard C Library Functions
                                                 pthread_attr_getstacksize(3C)



NAME
       pthread_attr_getstacksize,   pthread_attr_setstacksize  -  get  or  set
       stacksize attribute

SYNOPSIS
       #include <pthread.h>

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


       int pthread_attr_setstacksize(pthread_attr_t *attr, size_t stacksize);

DESCRIPTION
       The functions  pthread_attr_setstacksize()  and  pthread_attr_getstack‐
       size(),  respectively,  set  and  get  the  thread  creation  stacksize
       attribute in the attr object.


       The stacksize attribute defines the minimum stack size (in bytes) allo‐
       cated  for  the  created  threads stack. When the stacksize argument is
       NULL, the default stack size becomes 1 megabyte  for  32-bit  processes
       and 2 megabytes for 64-bit processes.

RETURN VALUES
       Upon    successful    completion,    pthread_attr_setstacksize()    and
       pthread_attr_getstacksize() return a value of 0.  Otherwise,  an  error
       number  is  returned  to indicate the error. The pthread_attr_getstack‐
       size() function stores the stacksize attribute value  in  stacksize  if
       successful.

ERRORS
       The pthread_attr_setstacksize() or pthread_attr_getstacksize() function
       may fail if:

       EINVAL    attr or stacksize is invalid.
