NAME
     getdtablesize - get descriptor table size

SYNOPSIS
     nfds = getdtablesize()
     int nfds;

DESCRIPTION
     Each process has a fixed size descriptor table, which is
     guaranteed to have at least 20 slots.  The entries in the
     descriptor table are numbered with small integers starting
     at 0.  The call _g_e_t_d_t_a_b_l_e_s_i_z_e returns the size of this
     table.
