       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.

       posix_spawnattr_getsigdefault, posix_spawnattr_setsigdefault -- get and
       set the spawn-sigdefault attribute of a spawn attributes object
       (AADDVVAANNCCEEDD RREEAALLTTIIMMEE)

       The _p_o_s_i_x___s_p_a_w_n_a_t_t_r___g_e_t_s_i_g_d_e_f_a_u_l_t() function shall obtain the value of
       the _s_p_a_w_n_-_s_i_g_d_e_f_a_u_l_t attribute from the attributes object referenced by
       _a_t_t_r.

       The _p_o_s_i_x___s_p_a_w_n_a_t_t_r___s_e_t_s_i_g_d_e_f_a_u_l_t() function shall set the _s_p_a_w_n_-
       _s_i_g_d_e_f_a_u_l_t attribute in an initialized attributes object referenced by
       _a_t_t_r.

       The _s_p_a_w_n_-_s_i_g_d_e_f_a_u_l_t attribute represents the set of signals to be
       forced to default signal handling in the new process image (if
       POSIX_SPAWN_SETSIGDEF is set in the _s_p_a_w_n_-_f_l_a_g_s attribute) by a spawn
       operation. The default value of this attribute shall be an empty signal
       set.

       return zero and store the value of the _s_p_a_w_n_-_s_i_g_d_e_f_a_u_l_t attribute of
       _a_t_t_r into the object referenced by the _s_i_g_d_e_f_a_u_l_t parameter; otherwise,
       an error number shall be returned to indicate the error.

       Upon successful completion, _p_o_s_i_x___s_p_a_w_n_a_t_t_r___s_e_t_s_i_g_d_e_f_a_u_l_t() shall
       return zero; otherwise, an error number shall be returned to indicate
       the error.
