PCW_DATA structure (wdm.h)

The PCW_DATA structure describes the data blocks that are associated with an instance. This structure is used with the PcwAddInstance and PcwCreateInstance functions. Most developers do not need to access this structure directly because it is automatically managed by the Add/Create helper functions generated by the CTRPP tool.

Syntax

typedef struct _PCW_DATA {
  const VOID *Data;
  ULONG      Size;
} PCW_DATA, *PPCW_DATA;

Members
