Description

Warning: ByteToCharLen is deprecated. Please use ElementToCharLen.

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

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

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

Note: ByteToCharLen will count a partial character if it appears as the last of the first MaxLen bytes.
