       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 functionality described on this reference page is aligned with the
       ISO C standard. Any conflict between the requirements described here
       and the ISO C standard is unintentional. This volume of POSIX.1-2008
       defers to the ISO C standard.

       These functions shall compute the quotient and remainder of the
       division of the numerator _n_u_m_e_r by the denominator _d_e_n_o_m.  If the
       division is inexact, the resulting quotient is the lloonngg integer (for
       the _l_d_i_v() function) or lloonngg lloonngg integer (for the _l_l_d_i_v() function) of
       lesser magnitude that is the nearest to the algebraic quotient. If the
       result cannot be represented, the behavior is undefined; otherwise,
       _q_u_o_t * _d_e_n_o_m+_r_e_m shall equal _n_u_m_e_r.

RREETTUURRNN VVAALLUUEE
       The _l_d_i_v() function shall return a structure of type llddiivv__tt, comprising
       both the quotient and the remainder. The structure shall include the
       following members, in any order:

           lloonngg   qquuoott;;    //** QQuuoottiieenntt **//
           lloonngg   rreemm;;     //** RReemmaaiinnddeerr **//

       The _l_l_d_i_v() function shall return a structure of type llllddiivv__tt,
       comprising both the quotient and the remainder. The structure shall
       include the following members, in any order:

           lloonngg lloonngg   qquuoott;;    //** QQuuoottiieenntt **//
