VOID GetInstance(
  LPSPropValue pvalMv,
  LPSPropValue pvalSv,
  ULONG uliInst
);

Parameters

  • pvalMv
    [in] Pointer to an SPropValue structure defining a multivalued property.

  • pvalSv
    [in] Pointer to a single-valued property to receive data.

  • uliInst
    [in] The instance number, that is, the array element, of the value being copied from the structure indicated by the pvalMv parameter.

Return Value

Remarks

If the value copied is too large for the allocated memory, the GetInstance function only copies pointers instead of allocating new memory.
