Detailed Description

The manipulate ELF library.

Define Documentation

#define MELF_ACCESS_ALL   (MELF_ACCESS_READ | MELF_ACCESS_WRITE)

Opening the ELF object for reading and writing.

#define MELF_ACCESS_READ   (1 << 0)

Opening the ELF object for reading.

#define MELF_ACCESS_WRITE   (1 << 1)

Opening the ELF object for writing.

#define MELF_HAS_ACCESS (  ctx, flag    )     ((ctx)->access & (flag))

Checks to see if the context has been opened readonly

---

Typedef Documentation

typedef struct _elf_spec_header ELF_SPEC_HEADER

ELF Specific header. Wrappers both section and program headers.

typedef struct _elf_spec_header_list ELF_SPEC_HEADER_LIST

Specific header list. A list that contains one or more specific headers.

typedef struct _melf MELF

MELF context. The melf context used to hold the path to an image as well as the elf, program and section headers.

---

Enumeration Type Documentation

enum ElfHeaderType

The ELF header type enumeration includes section and program.

Function Documentation

void melf_destroy (  MELF *    melf )

Destroys a MELF context, deallocating all memory associated with it. Parameters: melf  [in] The context to destroy. Examples: new.c.

MELF* melf_new (    )

Creates a blank MELF context. Returns: On success, a newly allocated MELF context is returned, otherwise NULL is returned. Examples: new.c.

MELF* melf_open (  const char *    image, int    access )

Translates an ELF image into a MELF context which can then be editted. The access parameter can be one of the following: MELF_ACCESS_READ Read access. MELF_ACCESS_WRITE Write access. MELF_ACCESS_ALL Read and Write access. Parameters: image  [in] The path to the image to edit. access  [in] What type of access to open the image with. Returns: On success, a newly allocated MELF context is returned, otherwise NULL is returned.

unsigned long melf_save (  MELF *    melf, const char *    path )

Saves a MELF context in ELF format to the specified path. Parameters: melf  [in] The context to translate from. path  [in] The path to the image to write to. Returns: On success, 1 is returned. Examples: new.c.

unsigned long melf_synchronize (  MELF *    melf )

Synchronizes the section and program headers as far as alignment and offsetting is concerned. This is an integral part of the saving process and can be used to make the in-memory version of the library appear as it would on disk if it were to be saved. Parameters: melf  [in] The melf context. Returns: The size, in bytes, of the image.

unsigned long melf_version (    )

Returns the version of the melf library. Returns: The version of the melf library.
