getBinding()

unsigned char elf::ELFSymbol::getBinding ( ) const

getType()

unsigned char elf::ELFSymbol::getType ( ) const

inline

Returns the type attribute of the st_info member.

Parse()

bool ELFSymbol::Parse	(	const lldb_private::DataExtractor &	data,
		lldb::offset_t *	offset
	)

Parse an ELFSymbol entry from the given DataExtractor starting at position offset.

The address size of the DataExtractor determines if a 32 or 64 bit object is to be parsed.

Parameters

[in]	data	The DataExtractor to read from. The address size of the extractor determines if a 32 or 64 bit object should be read.
[in,out]	offset	Pointer to an offset in the data. On return the offset will be advanced by the number of bytes read.

Returns

True if the ELFSymbol was successfully read and false otherwise.
