ELF_GETPHNUM(3) BSD Library Functions Manual ELF_GETPHNUM(3)NAME
elf_getphnum -- return the number of program headers in an ELF file
LIBRARY
ELF Access Library (libelf, -lelf)
SYNOPSIS
#include <libelf.h>
int
elf_getphnum(Elf *elf, size_t *phnum);
DESCRIPTION
Function elf_getphnum() retrieves the number of ELF program headers associated with descriptor elf and stores it into the location pointed to
by argument phnum.
This routine allows applications to uniformly process both normal ELF objects and ELF objects that use extended numbering.
RETURN VALUES
Function elf_getphnum() returns a non-zero value if successful, or zero in case of an error.
ERRORS
Function elf_getphnum() can fail with the following errors:
[ELF_E_ARGUMENT] A NULL value was passed in for argument elf.
[ELF_E_ARGUMENT] Argument elf was not for an ELF file.
[ELF_E_ARGUMENT] Argument elf lacks an ELF Executable Header.
[ELF_E_HEADER] The ELF Executable Header associated with argument elf was corrupt.
[ELF_E_SECTION] The section header at index SHN_UNDEF was corrupt.

Dear Group,
I want to prepare an ELF file which can be downloaded dynamically to any address in the moemory and executes as a new task/thread/process.
1) for this what are all the compileation, linker options while building the ELF file?
2) which parts of ELF file has to modified while... (1 Reply)
I have a script file that file type is
ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs)
Now I want to get the contents of this file. How can I ?
Any help me to get cotents of this file type? (2 Replies)
