Пролог (Prolog)

This manual page is part of the POSIX Programmer's Manual.  The
       Linux implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior),
       or the interface may not be implemented on Linux.

Имя (Name)

pthread_attr_getstacksize, pthread_attr_setstacksize — get and
       set the stacksize attribute

Синопсис (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);

Описание (Description)

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

The stacksize attribute shall define the minimum stack size (in bytes) allocated for the created threads stack.

The behavior is undefined if the value specified by the attr argument to pthread_attr_getstacksize() or pthread_attr_setstacksize() does not refer to an initialized thread attributes object.

Возвращаемое значение (Return value)

Upon successful completion, pthread_attr_getstacksize() and
       pthread_attr_setstacksize() shall return a value of 0; otherwise,
       an error number shall be returned to indicate the error.

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

Ошибки (Error)

The pthread_attr_setstacksize() function shall fail if:

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

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

       The following sections are informative.

Примеры (Examples)

None.

Использование в приложениях (Application usage)

None.

Обоснование (Rationale)

If an implementation detects that the value specified by the attr
       argument to pthread_attr_getstacksize() or
       pthread_attr_setstacksize() does not refer to an initialized
       thread attributes object, it is recommended that the function
       should fail and report an [EINVAL] error.

Будущие направления (Future directions)

None.
