Description

Returns the number of characters fully contained in the first MaxLen elements of a string.

Call ElementToCharLen to determine the number of characters represented by a portion of a string. ElementToCharLen counts characters until it reaches MaxLen elements or the end of the string, whichever comes first.

When working with multi-byte character systems (MBCS), the value returned by ElementToCharLen may be less than MaxLen or than the length of the string.

Note: ElementToCharLen counts a partial character if it appears as the last character of the first MaxLen elements.
