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

       pthread_attr_getstacksize, pthread_attr_setstacksize -- get and set the
       stacksize attribute

       #include <pthread.h>

       int pthread_attr_getstacksize(const pthread_attr_t *restrict _a_t_t_r,
           size_t *restrict _s_t_a_c_k_s_i_z_e);
       int pthread_attr_setstacksize(pthread_attr_t *_a_t_t_r, size_t _s_t_a_c_k_s_i_z_e);

DDEESSCCRRIIPPTTIIOONN
       The _p_t_h_r_e_a_d___a_t_t_r___g_e_t_s_t_a_c_k_s_i_z_e() and _p_t_h_r_e_a_d___a_t_t_r___s_e_t_s_t_a_c_k_s_i_z_e()
       functions, respectively, shall get and set the thread creation
       _s_t_a_c_k_s_i_z_e attribute in the _a_t_t_r object.

       The _s_t_a_c_k_s_i_z_e 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 _a_t_t_r argument
       to _p_t_h_r_e_a_d___a_t_t_r___g_e_t_s_t_a_c_k_s_i_z_e() or _p_t_h_r_e_a_d___a_t_t_r___s_e_t_s_t_a_c_k_s_i_z_e() does not
       refer to an initialized thread attributes object.

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

       The _p_t_h_r_e_a_d___a_t_t_r___g_e_t_s_t_a_c_k_s_i_z_e() function stores the _s_t_a_c_k_s_i_z_e attribute
       value in _s_t_a_c_k_s_i_z_e if successful.

EERRRROORRSS
       The _p_t_h_r_e_a_d___a_t_t_r___s_e_t_s_t_a_c_k_s_i_z_e() function shall fail if:

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

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

       _T_h_e _f_o_l_l_o_w_i_n_g _s_e_c_t_i_o_n_s _a_r_e _i_n_f_o_r_m_a_t_i_v_e_.

EEXXAAMMPPLLEESS
       None.

AAPPPPLLIICCAATTIIOONN UUSSAAGGEE
       None.

RRAATTIIOONNAALLEE
       If an implementation detects that the value specified by the _a_t_t_r
       argument to _p_t_h_r_e_a_d___a_t_t_r___g_e_t_s_t_a_c_k_s_i_z_e() or _p_t_h_r_e_a_d___a_t_t_r___s_e_t_s_t_a_c_k_s_i_z_e()
       does not refer to an initialized thread attributes object, it is
       recommended that the function should fail and report an [[EEIINNVVAALL]] error.
