Member Function Documentation

NextNote()

ElfImageReader::NoteReader::Result crashpad::ElfImageReader::NoteReader::NextNote	(	std::string *	name,
		NoteType *	type,
		std::string *	desc,
		VMAddress *	desc_addr )

Searches for the next note in the image.

Parameters

[out]	name	The name of the note owner, if not nullptr.
[out]	type	A type for the note, if not nullptr.
[out]	desc	The note descriptor.
[out]	desc_addr	The address in the remote process' address space desc was read from.

Returns

a Result value. name, type, desc, and desc_addr are only valid if this method returns Result::kSuccess.
