  NAME

    end, etext, edata - The last locations in a program

  LIBRARY

    Standard C Library (libc.a)

  SYNOPSIS

    extern end ;

    extern etext ;

    extern edata ;

  DESCRIPTION

    These names refer neither to functions nor to locations with interesting
    contents.  The address of etext is the first address above the program
    text, the address of edata above the initialized data region, and the
    address of 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
    functions of brk(), malloc(), standard input/output stdio(), the profile
    (-p) flag of the cc command, and in other ways.  Thus, the current value
    of the program break should be determined by sbrk (char *)(0).  See brk().

  EXAMPLES

    This example shows a code fragment which gets the program break and
    assumes that the break has not been reset by brk(), malloc(), or by any
    other means:

         .
         .
         .
    extern end;
    unsigned int break;

    /* get the program break - assumes the break has not been reset */
    /* by brk(), malloc(), etc. */
         break = &end;
         .
         .
         .
