RtlULongToLong function (ntintsafe.h)

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

Syntax

NTSTATUS RtlULongToLong(
  [in]  ULONG ulOperand,
  [out] LONG  *plResult
);

Parameters

[in] ulOperand

The value to be converted.

[out] plResult

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.
