toInt()

template<typename INT >

INT etiss::plugin::gdb::hex::toInt	(	const std::string &	string,
		bool	isLittleEndian,
		size_t	pos = 0

template<typename INT >

INT etiss::plugin::gdb::hex::tryInt	(	std::string &	string,
		unsigned &	pos,
		size_t	maxlength = sizeof(INT) * 2
	)

parses a hex string and returns the result.

the string will be parsed until the end is reached, an invalid character was encountered or maxlength was reached. this function cannot handle a "0x" prefix

Parameters

string	string to parse;
pos	current position in the string. will be set to the index of the first character that was not part of the returned value
maxlength	maximum parse length in characters (may be uneven)
