LongToIntPtr function (intsafe.h)
Converts a value of type LONG to a value of type INT_PTR.
Syntax
HRESULT LongToIntPtr(
[in] LONG lOperand,
[out] INT_PTR *piResult
);
Parameters
[in] lOperand
Type: LONG
The value to be converted.
[out] piResult
Type: INT_PTR*
A pointer to the converted value. In the case where the conversion causes a truncation of the original value, the function returns INTSAFE_E_ARITHMETIC_OVERFLOW and this parameter is not valid.
Return value
Type: HRESULT
If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
This is one of a set of inline functions designed to provide type conversions and perform validity checks with minimal impact on performance.
LongToPtrdiffT is an alias for this function.
