END(3C)                              SysV                              END(3C)



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 etext is the first address above the program
     text, edata above the initialized data region, and end above the
     uninitialized data region.

     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 of brk(2), malloc(3C), standard input/output [stdio(3S)], the
     profile (-p) option of cc(1), and so on.  Thus, the current value of the
     program break should be determined by sbrk (char *)(0) [see brk(2)].
