string_from_unterminated()

std::string string_from_unterminated	(	const char *	data,
		size_t	data_length
	)

Convert a (potentially not null terminated) array into a std::string.

Convert a C style string that may or may not be null terminated safely into a std::string. The string's termination is either set at the first \0 or after data_length characters.

Parameters

[in]	data	A c-string from which the std::string shall be constructed. Does not need to be null terminated.
[in]	data_length	An upper bound for the string length (must be at most the allocated length of buffer). If no null terminator is found in data, then the resulting std::string will be null terminated at data_length.
