Member Function Documentation

◆ Parse()

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

Parse an ELFSectionHeader entry from the given DataExtracter starting at position offset.

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 ELFSectionHeader was successfully read and false otherwise.
