       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.

       The _s_c_h_e_d___r_r___g_e_t___i_n_t_e_r_v_a_l() function shall update the ttiimmeessppeecc
       structure referenced by the _i_n_t_e_r_v_a_l argument to contain the current
       execution time limit (that is, time quantum) for the process specified
       by _p_i_d.  If _p_i_d is zero, the current execution time limit for the
       calling process shall be returned.

       If successful, the _s_c_h_e_d___r_r___g_e_t___i_n_t_e_r_v_a_l() function shall return zero.
       Otherwise, it shall return a value of -1 and set _e_r_r_n_o to indicate the
       error.

       The _s_c_h_e_d___r_r___g_e_t___i_n_t_e_r_v_a_l() function shall fail if:
