PTHREAD_ATTR_SETSTACKSIZE(OpenBSD   Programmer's   ManPTHREAD_ATTR_SETSTACKSIZE(3)

NAME    [Toc]    [Back]

     pthread_attr_setstacksize, pthread_attr_getstacksize  -  set
and get stacksize
 attribute

SYNOPSIS    [Toc]    [Back]

     #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);

DESCRIPTION    [Toc]    [Back]

     The functions pthread_attr_setstacksize() and
     pthread_attr_getstacksize(),  respectively,  set and get the
thread creation
 stacksize attribute in the attr object.

     The stacksize attribute defines the minimum stack  size  (in
bytes) allocated
 for the created thread's stack.

RETURN VALUES    [Toc]    [Back]

     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_getstacksize()   function   stores    the
stacksize attribute
     value in stacksize if successful.

ERRORS    [Toc]    [Back]

     The pthread_attr_setstacksize() function will fail if:

     [EINVAL]        The   value   of   stacksize  is  less  than
PTHREAD_STACK_MIN or
                   exceeds a system-imposed limit.

     These functions will not return an error code of [EINTR].
