RtlPtrdiffTSub function (ntintsafe.h)

  • Artikel

Subtracts one value of type PTRDIFF_T from another.

Syntax

NTSTATUS RtlPtrdiffTSub(
  [in]  ptrdiff_t Minuend,
  [in]  ptrdiff_t Subtrahend,
  [out] ptrdiff_t *pResult
);

Parameters

[in] Minuend

The value from which Subtrahend is subtracted.

[in] Subtrahend

The value to subtract from Minuend.

[out] pResult

A pointer to the result. If the operation results in a value that overflows or underflows the capacity of the type, 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 arithmetic operations and perform validity checks with minimal impact on performance.
