<H2>DESCRIPTION</H2><PRE>
|
||||
These names refer neither to routines nor to locations with interesting
|
||||
contents. The address of <STRONG>etext</STRONG> is the first address above the program
|
||||
text, <STRONG>edata</STRONG> above the initialized data region, and <STRONG>end</STRONG> above the
|
||||
uninitialized data region. <STRONG>_end</STRONG> is the same as <STRONG>end</STRONG>, but in the
|
||||
implementers name space, i.e. for use in libraries.
|
||||
|
||||
When execution begins, the program break coincides with <STRONG>end</STRONG>, but it is
|
||||
reset by the routines <STRONG><A HREF="../man2/brk.2.html">brk(2)</A></STRONG>, <STRONG><A HREF="../man3/malloc.3.html">malloc(3)</A></STRONG>, standard input/output
|
||||
(<STRONG><A HREF="../man3/stdio.3.html">stdio(3)</A></STRONG>), etc. The current value of the program break is reliably
|
||||
returned by `<STRONG><A HREF="../man0/sbrk.0.html">sbrk(0)</A></STRONG>', see <STRONG><A HREF="../man2/brk.2.html">brk(2)</A></STRONG>.
