RE: How to access an applications ELF program header and ELF section header at runtime

["Bharath Ramesh" <bramesh at vt dot edu>]

Thanks for the reply, are these symbols __data_start, __bss_start specific
to Linux or would they work under any GNU system running a different kernel.
I am trying to keep my work portable to any system that uses GNU libc, but
not particularly the Linux kernel.

Regards,

Bharath

Hi Bharath,

Have a look at the symbols __data_start, _edata, __bss_start and _end.

Eduardo
