1) OclElf(eclass, rawElfBytes, rawElfSize, 0, ELF_C_READ)
To load ELF from raw bytes in memory and generate OclElf object. And this
object is for reading only.
2) OclElf(eclass, NULL, 0, elfFileName|NULL, ELF_C_WRITE)
To create an ELF for writing and save it into a file 'elfFileName' (if it
is NULL, the OclElf will create a temporary file and set it to 'elfFileName'.
Since we need to read the ELF into memory, this file 'elfFileName' is created
with both read and write, so that the runtime can use dumpImage() to get ELF
raw bytes by reading this file.
'eclass' is ELF's bitness and it must be the same as the eclass of ELF to
be loaded (for example, rawElfBytes).

/* Bucket expansion has the effect of doubling the number of buckets
* and redistributing the items into the new buckets. Ideally the
* items will distribute more or less evenly into the new buckets
* (the extent to which this is true is a measure of the quality of
* the hash function as it applies to the key domain).
*
* With the items distributed into more buckets, the chain length
* (item count) in each bucket is reduced. Thus by expanding buckets
* the hash keeps a bound on the chain length. This bounded chain
* length is the essence of how a hash provides constant time lookup.
*
* The calculation of tbl->ideal_chain_maxlen below deserves some
* explanation. First, keep in mind that we're calculating the ideal
* maximum chain length based on the *new* (doubled) bucket count.
* In fractions this is just n/b (n=number of items,b=new num buckets).
* Since the ideal chain length is an integer, we want to calculate
* ceil(n/b). We don't depend on floating point arithmetic in this
* hash, so to calculate ceil(n/b) with integers we could write
*
* ceil(n/b) = (n/b) + ((n%b)?1:0)
*
* and in fact a previous version of this hash did just that.
* But now we have improved things a bit by recognizing that b is
* always a power of two. We keep its base 2 log handy (call it lb),
* so now we can write this with a bit shift and logical AND:
*
* ceil(n/b) = (n>>lb) + ( (n & (b-1)) ? 1:0)

/*
* This file defines five types of data structures: singly-linked lists,
* lists, simple queues, tail queues, and circular queues.
*
* A singly-linked list is headed by a single forward pointer. The
* elements are singly linked for minimum space and pointer manipulation
* overhead at the expense of O(n) removal for arbitrary elements. New
* elements can be added to the list after an existing element or at the
* head of the list. Elements being removed from the head of the list
* should use the explicit macro for this purpose for optimum
* efficiency. A singly-linked list may only be traversed in the forward
* direction. Singly-linked lists are ideal for applications with large
* datasets and few or no removals or for implementing a LIFO queue.
*
* A list is headed by a single forward pointer (or an array of forward
* pointers for a hash table header). The elements are doubly linked
* so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before
* or after an existing element or at the head of the list. A list
* may only be traversed in the forward direction.
*
* A simple queue is headed by a pair of pointers, one the head of the
* list and the other to the tail of the list. The elements are singly
* linked to save space, so elements can only be removed from the
* head of the list. New elements can be added to the list after
* an existing element, at the head of the list, or at the end of the
* list. A simple queue may only be traversed in the forward direction.
*
* A tail queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or
* after an existing element, at the head of the list, or at the end of
* the list. A tail queue may be traversed in either direction.
*
* A circle queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or after
* an existing element, at the head of the list, or at the end of the list.
* A circle queue may be traversed in either direction, but has a more
* complex end of list detection.
*
* For details on the use of these macros, see the queue(3) manual page.

libelf: a BSD-licensed implementation of the ELF(3)/GELF(3) API.
Documentation:
* Manual page elf.3 contains an overview of the library. Other
manual pages document individual APIs in the library.
* A tutorial "libelf by Example" is available at:
http://people.freebsd.org/~jkoshy/download/libelf/article.html
For ongoing development please see http://elftoolchain.sourceforge.net/

: README.build -- notes on the build process
The "Makefile" in this directory uses BSD make(1) syntax. If you are
trying to build this library on a platform that does not have a
pre-built BSD compatible make(1), then you could try porting NetBSD's
make(1). NetBSD's make(1) is available at:
http://www.crufty.net/help/sjg/bmake.html
: Supporting cross builds
In the general case, libelf may be built for a target operating system
and machine architecture that is different from the host operating
system and machine architecture that the compilation is happening on.
For example, compilation could be running on a Linux/i386 host, with
target binaries being created for a NetBSD/sparc64 system.
To support cross building:
- The top-level "Makefile" pulls in the appropriate make rules for the
target system.
Inside of makefiles, we determine the target OS by looking at the
contents of the ${unix} make variable. The top-level makefile then
includes any target specific makefiles if they exist.
- Operating systems differ in the names and locations of the headers
where their ELF types are defined. They also differ in the set of
ELF types supported. Inside of libelf's implementation these
differences are abstracted out by the auxiliary header
"_libelf_config.h".
: OS Specific Configuration :
:: Debian ::
The following packages are needed for the build:
- `build-essential'
- `m4'
- `freebsd-buildutils' or `freebsd5-buildutils'
You would need to use `freebsd-make' instead of GNU make to build
the tools. You would also need to place /usr/lib/freebsd in the
shell's `PATH', preferably at the beginning.
:: FreeBSD ::
libelf should build out of the box on FreeBSD versions later than 6.0.
:: NetBSD ::
libelf should build out of the box on NetBSD versions later than 4.0.
:: Ubuntu ::
See the section on 'Debian' above.
: Porting resources on the 'net
The 'predef' project [http://predef.sourceforge.net/] has a
comprehensive list of CPP macros predefined by various OSes.

/*
* `ar' archive handling.
*
* `ar' archives start with signature `ARMAG'. Each archive member is
* preceded by a header containing meta-data for the member. This
* header is described in <ar.h> (struct ar_hdr). The header always
* starts on an even address. File data is padded with "\n"
* characters to keep this invariant.
*
* Special considerations for `ar' archives:
*
* There are two variants of the `ar' archive format: traditional BSD
* and SVR4. These differ in the way long file names are treated, and
* in the layout of the archive symbol table.
*
* The `ar' header only has space for a 16 character file name.
*
* In the SVR4 format, file names are terminated with a '/', so this
* effectively leaves 15 characters for the actual file name. Longer
* file names stored in a separate 'string table' and referenced
* indirectly from the name field. The string table itself appears as
* an archive member with name "// ". An `indirect' file name in an
* `ar' header matches the pattern "/[0-9]*". The digits form a
* decimal number that corresponds to a byte offset into the string
* table where the actual file name of the object starts. Strings in
* the string table are padded to start on even addresses.
*
* In the BSD format, file names can be upto 16 characters. File
* names shorter than 16 characters are padded to 16 characters using
* (ASCII) space characters. File names with embedded spaces and file
* names longer than 16 characters are stored immediately after the
* archive header and the name field set to a special indirect name
* matching the pattern "#1/[0-9]+". The digits form a decimal number
* that corresponds to the actual length of the file name following
* the archive header. The content of the archive member immediately
* follows the file name, and the size field of the archive member
* holds the sum of the sizes of the member and of the appended file
* name.
*
* Archives may also have a symbol table (see ranlib(1)), mapping
* program symbols to object files inside the archive.
*
* In the SVR4 format, a symbol table uses a file name of "/ " in its
* archive header. The symbol table is structured as:
* - a 4-byte count of entries stored as a binary value, MSB first
* - 'n' 4-byte offsets, stored as binary values, MSB first
* - 'n' NUL-terminated strings, for ELF symbol names, stored unpadded.
*
* In the BSD format, the symbol table uses a file name of "__.SYMDEF".
* It is structured as two parts:
* - The first part is an array of "ranlib" structures preceded by
* the size of the array in bytes. Each "ranlib" structure
* describes one symbol. Each structure contains an offset into
* the string table for the symbol name, and a file offset into the
* archive for the member defining the symbol.
* - The second part is a string table containing NUL-terminated
* strings, preceded by the size of the string table in bytes.
*
* If the symbol table and string table are is present in an archive
* they must be the very first objects and in that order.
