Hi rongz,

you mean read the contents of the executable in the executable?
If you are using C, fopen it (argv[0]) and use fread to read until EOF .... That should suffice

Cheers!

no, I mean how to access ELF header (e.g. retrieve information encoded in ELF header) in an ELF format file.

or go to www.wotsit.org and downloaf ELF file format. All you need to do is fopen the ELF file and fread(or fscanf) the header into the structs which are defined in the file format specification
