◆ ByteLengthMBS()

std:: size_t Chusov::String::ByteLengthMBS	(	const char *	pszString,
		std::size_t	cchInput
	)

noexcept

Returns a number of bytes occupied by the cchInput multibyte symbols of a string.

Parameters

[in]	pszString	is the string of cchInput multibyte characters. The string need not to be zero-terminated unless cchInput is (size_t) -1.
[in]	cchInput	is a size of the string in multibyte characters corresponding to the returned byte size.

Returns: The function returns a number of bytes occupied by the string or (size_t) -1 if error occurs. Use GetLastChsvError to get extended information. If the input string contains an invalid multibyte character the error code set is CHSVERROR_INVALID_CHAR_SEQUENCE.

Remarks: If null character is met within cchInput symbols, then it is ignored together with the rest symbols and bytes.; cchInput (or the null character) must specify the total number of complete characters in the string. Otherwise the behaviour is undefined.; If the last part of the string contains an incomplete but potentially valid character, it is ignored by the function.
