NAME
end, edata, etext, __data_start, __text_start - last locations in program
SYNOPSIS
DESCRIPTION
These names refer neither to routines nor to locations with interesting contents. The address of the symbols and is the first address
above the program text. The address of and is the first address above the initialized data region. The address of and is the first
address above the uninitialized data region.
The address of the symbol is the beginning address of the program's data area, and is the beginning address of the program's text area.
The linker defines these symbols with the appropriate values if they are referenced by the program but not defined. The linker issues an
error if the user attempts to define or
When execution begins, the program break (the first location beyond the data) coincides with but the program break can be reset by the rou-
tines of brk(2), malloc(3C), standard input/output (stdio(3S)), the profile option of cc(1), and so on. Thus, the current value of the
program break should be determined by (see brk(2)).
WARNINGS
In C, these names must look like addresses. Thus, use instead of to access the current value of end.
