       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_spawn_file_actions_destroy, posix_spawn_file_actions_init --

       The _p_o_s_i_x___s_p_a_w_n___f_i_l_e___a_c_t_i_o_n_s___d_e_s_t_r_o_y() function shall destroy the
       object referenced by _f_i_l_e___a_c_t_i_o_n_s; the object becomes, in effect,
       uninitialized. An implementation may cause
       _p_o_s_i_x___s_p_a_w_n___f_i_l_e___a_c_t_i_o_n_s___d_e_s_t_r_o_y() to set the object referenced by
       _f_i_l_e___a_c_t_i_o_n_s to an invalid value. A destroyed spawn file actions object
       can be reinitialized using _p_o_s_i_x___s_p_a_w_n___f_i_l_e___a_c_t_i_o_n_s___i_n_i_t(); the results
       of otherwise referencing the object after it has been destroyed are
       undefined.

       The _p_o_s_i_x___s_p_a_w_n___f_i_l_e___a_c_t_i_o_n_s___i_n_i_t() function shall initialize the
       object referenced by _f_i_l_e___a_c_t_i_o_n_s to contain no file actions for
       _p_o_s_i_x___s_p_a_w_n() or _p_o_s_i_x___s_p_a_w_n_p() to perform.

       A spawn file actions object is as defined in
       _p_o_s_i_x___s_p_a_w_n___f_i_l_e___a_c_t_i_o_n_s___a_d_d_c_l_o_s_e().

       The effect of initializing an already initialized spawn file actions
       object is undefined.

RREETTUURRNN VVAALLUUEE
       Upon successful completion, these functions shall return zero;
       otherwise, an error number shall be returned to indicate the error.

       The _p_o_s_i_x___s_p_a_w_n___f_i_l_e___a_c_t_i_o_n_s___i_n_i_t() function shall fail if:

       EENNOOMMEEMM Insufficient memory exists to initialize the spawn file actions
              object.

       The _p_o_s_i_x___s_p_a_w_n___f_i_l_e___a_c_t_i_o_n_s___d_e_s_t_r_o_y() function may fail if:

       EEIINNVVAALL The value specified by _f_i_l_e___a_c_t_i_o_n_s is invalid.
