ACI Structures

This chapter describes the structures used by the ACI functions.

Here is an example of the structure syntax:

typedef struct tagACI_Buffer_Params

{

 UINT   Size;             // (in)  Size of structure, in bytes

 DWORD  Layer0SizeLow;    // (in || out) Low 32 bits of layer 0 size, in bytes

 DWORD  Layer0SizeHigh;   // (in || out) High 32 bits of layer 0 size, in bytes

                          //       Layer size is rounded up to a nearest value supported by programmer.

 LPCSTR BufferName;       // (in)  Buffer name

 UINT   BufferNumber;     // For ACI_CreateBuffer(): out: Created buffer number

                          // For ACI_ReallocBuffer(): in: Buffer number to realloc

 UINT   NumBuffers;       // (out) Total number of currently allocated buffers

 UINT   NumLayers;        // (out) Total number of layers in a buffer

} ACI_Buffer_Params;

Each structure includes a number of parameters (here Size, Layer0SizeLow, NumBuffers, etc.). The parameter's name follows its format (UINT, DWORD, LPCSTR, CHAR, BOOL, etc.). The comment on the parameter begins from a bracketed symbol showing the sending direction of this parameter:
