NAME

       elf_getdata - Get washed data of section

SYNOPSIS

       #include <libelf.h>

       Elf_Data * elf_getdata (Elf_Scn *scn, Elf_Data *data);

DESCRIPTION

       The elf_getdata() function allows the user to retrieve the data buffers of the section scn
        .  There  can be more than one buffer if the user explicitly added them.  When a file is read the libelf
       library creates exactly one data buffer.

       The first buffer in the list can be obtained by passing a null pointer in the parameter data. To get  the
       next data buffer the previously returned value must be passed in the data parameter. If there are no more
       buffer left in the list a null pointer is returned.

       If the data parameter is not a null pointer it must be a descriptor for  a  buffer  associated  with  the
       section  scn  .  If  this  is  not  the  case  a  null  pointer is returned. To facilitate error handling
       elf_getdata also returns a null pointer if the scn parameter is a null pointer.
