示例1: ReadMem
int ReadMem(kMemory* pk_Mem, void* buffer, UINT count)
{
if (mu32_BlockSize > 0) // read from the blocks in memory (Cache)
{
// Cabinet.dll opens two handles to the CAB file
// The data in the first block of the CAB file is read multiple times by BOTH handles
if (pk_Mem->s32_Pos + count < mu32_BlockSize)
return mi_FirstBlock.ReadData(buffer, pk_Mem->s32_Pos, count);
// One CAB file handle reads the CAB index (filenames)
// The other handle reads the compressed data
// To avoid unneccessary downloads each CAB file handle has its own cache
DWORD u32_Cache = (DWORD)(INT_PTR) pk_Mem->p_Addr;
return mi_Cache[u32_Cache].ReadData(buffer, pk_Mem->s32_Pos, count);
}
else // read from the downloaded file on disk
{
SetFilePointer(mi_Internet.GetDownloadFile(), pk_Mem->s32_Pos, 0, FILE_BEGIN);
DWORD u32_Read;
if (!ReadFile(mi_Internet.GetDownloadFile(), buffer, count, &u32_Read, 0))
{
mi_Error.Set(FDIERROR_READ_CABFILE, GetLastError(),0);
return -1;
}
