NdisAllocateMemoryWithTagPriority (Compact 2013)

  • 아티클

3/26/2014

NDIS drivers call this function to allocate a pool of memory from the nonpaged pool.

Syntax

PVOID
  NdisAllocateMemoryWithTagPriority(
    IN NDIS_HANDLE  NdisHandle,
    IN UINT  Length,
    IN ULONG  Tag,
    IN EX_POOL_PRIORITY  Priority
    );

Parameters

  • NdisHandle
    An NDIS handle that the caller obtained during initialization.
  • Length
    The size to be allocated, in bytes.
  • Tag
    A string, delimited by single quotation marks, with up to four characters, usually specified in reversed order. The NDIS-supplied default tag for this call is 'maDN'. However, the caller can override this default by supplying an explicit value.
  • Priority
    The importance of this request

Return Value

NdisAllocateMemoryWithTagPriority returns a pointer to a base virtual address of the allocated memory, or NULL if sufficient nonpaged memory is currently unavailable.

Remarks

A call to NdisAllocateMemoryWithTagPriority is the same as calling the NdisAllocateMemoryWithTag, function except that NdisAllocateMemoryWithTagPriority allows the caller to supply the priority of the request.
