NAME
       end, etext, edata - last locations in program

SYNOPSIS
       extern end;
       extern etext;
       extern edata;

DESCRIPTION
       These names refer neither to routines nor to locations with interesting
       contents.  The address of _e_t_e_x_t is the first address above the  program
       text, _e_d_a_t_a above the initialized data region, and _e_n_d above the unini‐
       tialized data region.

       When execution begins, the program break coincides with _e_n_d_, but it  is
       reset   by   the  routines  _b_r_k(2),  _m_a_l_l_o_c(3),  standard  input/output
       (_s_t_d_i_o(3S)), the profile (-p) option of _c_c(1), etc.  The current  value
       of the program break is reliably returned by ‘sbrk(0)’, see _b_r_k(2).

SEE ALSO
