     elf_getphdrnum(Elf *elf, size_t *phnum);

DESCRIPTION
     Function elf_getphdrnum() 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.

     case of an error.

     Function elf_getphdrnum() 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.
