RtlLongToULongPtr function (ntintsafe.h)

Converts a value of type LONG to a value of type ULONG_PTR.

Syntax

NTSTATUS RtlLongToULongPtr(
  LONG      lOperand,
  ULONG_PTR *pulResult
);

Parameters

lOperand

The value to be converted.

pulResult

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.

Return value

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:

  • RtlLongToDWordPtr
  • RtlLongToSIZET
