.SH NAME
elf_rawfile \- Retrieve a pointer to the entire raw ELF file image

.SH SYNOPSIS
.nf
#include <libelf.h>

.BI "char *elf_rawfile(Elf *" elf ", size_t *" ptr ");"
.fi

.SH DESCRIPTION
The
.BR elf_rawfile ()
function returns a pointer to the entire contents of the ELF file represented by
.IR elf .
This data is unprocessed and includes everything from the ELF header to the
final byte.

If the ELF descriptor was opened from memory or the file has already been
memory-mapped or fully read, this function returns a pointer to the internal buffer.

If the ELF data has not yet been read or mapped, it is loaded on demand.

If
.I ptr
is non-NULL, the total size in bytes of the raw file is stored in
.IR *ptr .

The returned buffer is read-only and managed internally by libelf.
The application must not modify or free it.

.SH PARAMETERS
.TP
.I elf
A handle previously returned by
.BR elf_begin (3) .

.TP
.I ptr
If not
.BR NULL ,
receives the size in bytes of the ELF file.

.SH RETURN VALUE
Returns a pointer to the start of the ELF file data. On failure,
.B NULL
is returned and
.I *ptr
(if non-NULL) is set to 0.
