Member Enumeration Documentation

CHARACTERISTICS

enum class LIEF::PE::Header::CHARACTERISTICS

strong

Enumerator
NONE
RELOCS_STRIPPED	The file does not contain base relocations and must be loaded at its preferred base. If this cannot be done, the loader will error.
EXECUTABLE_IMAGE	File is executable (i.e. no unresolved externel references).
LINE_NUMS_STRIPPED	COFF line numbers have been stripped. This is deprecated and should be 0
LOCAL_SYMS_STRIPPED	COFF symbol table entries for local symbols have been removed. This is deprecated and should be 0.
AGGRESSIVE_WS_TRIM	Aggressively trim working set. This is deprecated and must be 0.
LARGE_ADDRESS_AWARE	Image can handle > 2GiB addresses.
BYTES_REVERSED_LO	Little endian: the LSB precedes the MSB in memory. This is deprecated and should be 0.
NEED_32BIT_MACHINE	Machine is based on a 32bit word architecture.
DEBUG_STRIPPED	Debugging info has been removed.
REMOVABLE_RUN_FROM_SWAP	If the image is on removable media, fully load it and copy it to swap.
NET_RUN_FROM_SWAP	If the image is on network media, fully load it and copy it to swap.
SYSTEM	The image file is a system file, not a user program.
DLL	The image file is a DLL.
UP_SYSTEM_ONLY	This file should only be run on a uniprocessor machine.
BYTES_REVERSED_HI	Big endian: the MSB precedes the LSB in memory. This is deprecated

inline

Characteristics of the binary like whether it is a DLL or an executable.

characteristics() [2/2]

void LIEF::PE::Header::characteristics ( uint32_t characteristics )

inline

characteristics_list()

std::vector< CHARACTERISTICS > LIEF::PE::Header::characteristics_list

(

)

const

The list of the CHARACTERISTICS.

create()

static Header LIEF::PE::Header::create ( PE_TYPE type )

static

has_characteristic()

bool LIEF::PE::Header::has_characteristic ( CHARACTERISTICS c ) const

inline

Check if the given CHARACTERISTICS is present.

machine() [1/2]

MACHINE_TYPES LIEF::PE::Header::machine ( ) const

inline

The targeted machine architecture like ARM, x86, AMD64, ...

machine() [2/2]

void LIEF::PE::Header::machine ( MACHINE_TYPES type )

inline

numberof_sections() [1/2]

uint16_t LIEF::PE::Header::numberof_sections ( ) const

inline

The number of sections in the binary.

numberof_sections() [2/2]

void LIEF::PE::Header::numberof_sections ( uint16_t nb )

inline

numberof_symbols() [1/2]

uint32_t LIEF::PE::Header::numberof_symbols ( ) const

inline

The number of entries in the symbol table. This data can be used to locate the string table which immediately follows the symbol table.

This value should be zero for an image because COFF debugging information is deprecated.

numberof_symbols() [2/2]

void LIEF::PE::Header::numberof_symbols ( uint32_t nb )

inline

operator=()

Header & LIEF::PE::Header::operator= ( const Header & )

default

pointerto_symbol_table() [1/2]

uint32_t LIEF::PE::Header::pointerto_symbol_table ( ) const

inline

The offset of the COFF symbol table.

This value should be zero for an image because COFF debugging information is deprecated.

pointerto_symbol_table() [2/2]

void LIEF::PE::Header::pointerto_symbol_table ( uint32_t ptr )

inline

remove_characteristic()

void LIEF::PE::Header::remove_characteristic ( CHARACTERISTICS c )

inline

signature() [1/2]

const signature_t & LIEF::PE::Header::signature ( ) const

inline

Signature (or magic byte) of the header. It must be: PE\0\0

signature() [2/2]

void LIEF::PE::Header::signature ( const signature_t & sig )

inline

sizeof_optional_header() [1/2]

uint16_t LIEF::PE::Header::sizeof_optional_header ( ) const

inline

Size of the OptionalHeader AND the data directories which follows this header.

This value is equivalent to: sizeof(pe_optional_header) + NB_DATA_DIR * sizeof(data_directory)

This size should be either:

• 0xE0 (224) for a PE32 (32 bits)
• 0xF0 (240) for a PE32+ (64 bits)
