elf_getdata \- Get washed data of section

.SH SYNOPSIS
|
|
.B #include <libelf.h>
|
|
.sp
|
|
.BI "Elf_Data * elf_getdata (Elf_Scn *" scn ", Elf_Data *" data ");"
|

|
.SH DESCRIPTION
|
|
The
|
|
.BR elf_getdata ()
|
|
function allows the user to retrieve the data buffers of the section
|
|
.I 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.
