Member Function Documentation

findByAddress()

std::optional< std::pair< codeview::PublicSym32, size_t > > PublicsStream::findByAddress	(	const SymbolStream &	Symbols,
		uint16_t	Segment,
		uint32_t	Offset ) const

Find a public symbol by a segment and offset.

In case there is more than one symbol (for example due to ICF), the first one is returned.

Returns

If a symbol was found, the symbol at the provided address is returned as well as the index of this symbol in the address map. If the binary was linked with ICF, there might be more symbols with the same address after the returned one. If no symbol is found, std::nullopt is returned.
