示例1: loadFromFile
int SoundDataManager::loadFromFile(const char* pFilePath)
{
int nSoundID = 0;
do
{
BREAK_IF(! FileUtils::isFileExisted(pFilePath));
int nID = BKDRHash(pFilePath);
// if we have loaded the file before,break
tEffectElement *pElement = NULL;
HASH_FIND_INT(m_pEffects, &nID, pElement);
if (pElement)
{
nSoundID = nID;
break;
}
// calculate the buffer size we needed
SoundPlayer TempPlayer;
int nBufferSize = TempPlayer.GetFileBufferSize(pFilePath);
// can not calculate the size,load failed
BREAK_IF(nBufferSize < 0);
// load the file data
unsigned char* buffer = NULL;
buffer = new unsigned char[nBufferSize];
BREAK_IF(!buffer);

// add the data to hash map
