RtlLongPtrToULong function

-description

Converts a value of type LONG_PTR to a value of type ULONG.

-parameters

-param lOperand [in]

The value to be converted.

-param pulResult [out]

A pointer to the converted value. In the case where the conversion causes a truncation of the original value, the function returns STATUS_INTEGER_OVERFLOW and this parameter is not valid.

-returns

Returns STATUS_SUCCESS if the operation is successful.

See the implementation of this helper function in ntintsafe.h in the WDK for possible error return values.

-remarks

This is one of a set of inline functions designed to provide type conversions and perform validity checks with minimal impact on performance.

This function uses the following alternate name:

• RtlLongPtrToDWord
• RtlSSIZETToULong
• RtlSSIZETToDWord
