  • Article

Subtracts one value of type UINT from another.

Syntax

NTSTATUS RtlUIntSub(
  [in]  UINT uMinuend,
  [in]  UINT uSubtrahend,

);

Parameters

[in] uMinuend

The value from which u8Subtrahend is subtracted.

[in] uSubtrahend

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