PCW_DATA structure

Description

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.

Members

`Data`

A pointer to a buffer of Size bytes containing a block of counter data.

`Size`

A numeric value that specifies the size, in bytes, of the Data buffer.
