WideStrUtils.WStrBufSize Function

Returns the maximum number of characters that can be stored in a PWideChar allocated by WStrAlloc.

Pascal

function WStrBufSize(const Str: PWideChar): Cardinal;

C++

unsigned WStrBufSize(const PWideChar Str);

WStrBufSize returns the number of characters in Str, including the byte for the termination character.

Note: If Str does not point to a string buffer allocated by WStrAlloc or WStrNew, no error message is returned, and the result is unpredictable.
