end(3C)             (C Programming Language Utilities)              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
         interesting 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 initialized
               data region.

         end   The address of end is the first address above the uninitialized
               data region.

   SEE ALSO
         cc(1), brk(2), malloc(3C), stdio(3S).

   NOTE
         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)].
