Member Function Documentation

◆ characteristics() [1/2]

uint32_t LIEF::COFF::Section::characteristics ( ) const

inline

Characteristics of the section: it provides information about the permissions of the section when mapped. It can also provide information about the purpose of the section (contain code, BSS-like, ...)

◆ characteristics() [2/2]

void LIEF::COFF::Section::characteristics ( uint32_t characteristics )

inline

◆ characteristics_list()

std::vector< CHARACTERISTICS > LIEF::COFF::Section::characteristics_list ( ) const

inline

List of the section characteristics.

References LIEF::PE::Section::characteristics_to_list().

◆ clear()

void LIEF::COFF::Section::clear ( uint8_t c )

inline

◆ comdat_info()

optional< ComdatInfo > LIEF::COFF::Section::comdat_info ( ) const

Return comdat infomration (only if the section has the CHARACTERISTICS::LNK_COMDAT characteristic)

◆ content() [1/2]

span< const uint8_t > LIEF::COFF::Section::content ( ) const

inlineoverridevirtual

Content wrapped by this section.

Reimplemented from LIEF::Section.

◆ content() [2/2]

void LIEF::COFF::Section::content ( const std::vector< uint8_t > & )

inlineoverridevirtual

Change section content.

Reimplemented from LIEF::Section.

◆ has_characteristic()

bool LIEF::COFF::Section::has_characteristic ( CHARACTERISTICS c ) const

inline

Check if the section has the given CHARACTERISTICS.

◆ has_extended_relocations()

bool LIEF::COFF::Section::has_extended_relocations ( ) const

inline

Whether there is a large number of relocations whose number need to be stored in the virtual address attribute.

◆ is_discardable()

bool LIEF::COFF::Section::is_discardable ( ) const

inline

True if the section can be discarded as needed.

This is typically the case for debug-related sections

◆ name() [1/2]

virtual std::string LIEF::Section::name ( ) const

inlinevirtual

section's name

Reimplemented from LIEF::Section.

◆ name() [2/2]

void LIEF::COFF::Section::name ( std::string name )

inline

Number of relocations.

Warning: If the number of relocations is greater than 0xFFFF (maximum value for 16-bits integer), then the number of relocations is stored in the virtual address of the first relocation.

inline

The file pointer to the beginning of line-number entries for the section.

This is set to zero if there are no COFF line numbers. This value should be zero for an image because COFF debugging information is deprecated and modern debug information relies on the PDB files.

void LIEF::COFF::Section::pointerto_line_numbers ( uint32_t ptr )

inline

◆ pointerto_raw_data() [1/2]
