end(3C)                                                             end(3C)

NAME
     end, etext, edata - last locations in program

SYNOPSIS
     extern etext;

     extern edata;

     extern end;

DESCRIPTION
     These names refer neither to routines nor to locations with interest-
     ing contents; only their addresses are meaningful.

     etext    The address of etext is the first address above the program
              text.

     edata    The address of edata is the first address above the initial-
              ized data region.

     end      The address of end is the first address above the uninitial-
              ized data region.

NOTES
     When execution begins, the program break (the first location beyond
     the data) coincides with end, but the program break may be reset by
     the routines brk, malloc, the standard input/output library [see
     stdio(3S)], by the profile (-p) option of cc, and so on. Thus, the
     current value of the program break should be determined by
     sbrk ((char *)0) [see brk(2)].
