UINT SysStringLen(BSTRbstr );

Parameters

Return Values

The number of characters in bstr, not including a terminating null character, indicates success.

If the bstr parameter is null, zero is returned.

Remarks

The returned value can be different from _fstrlen(bstr) if the following occurred:

For a BSTR allocated with SysAllocStringLen, SysAllocStringLen, or SysAllocStringByteLen, the SysStringLen function retrieves the number of characters specified in the cch parameter at allocation time.

Windows CE supports only Unicode strings.

Passing invalid (and under some circumstances NULL) pointers to this function causes an unexpected termination of the application.
