       end, etext, edata - Defines the last location of a program

       extern end; extern etext; extern edata;

       The  external names end, etext, and edata are defined for all programs.
       They are not functions, but identifiers associated with	the  following
       addresses:  The	first  address	following the program text.  The first
       address following the initialized data region.  The first address  fol‐
       lowing the data region that is not initialized.

       The  break  value of the program is the first location beyond the data.
       When a program begins running, this location coincides with end.	  How‐
       ever,  many  factors  can  change the break value, including: The brk()
       function The malloc() function The standard I/O functions The  -p  flag
       on the cc command

       Therefore,  use	sbrk(0),  not end, to determine the break value of the

       Functions: brk(2), malloc(3)

       Commands: cc(1)
