示例1: wxASSERT
void WaveTrack::Read64K(sampleType * buffer, WaveBlock * b,
sampleCount start, sampleCount len)
{
wxASSERT(b);
wxASSERT(start >= 0);
wxASSERT(start + len <= ((b->len + 65535) / 65536));
start *= 2;
len *= 2;
BlockFile *f = b->f;
bool opened = f->OpenReadHeader();
wxASSERT(opened);
f->SeekTo(headerTagLen + start * sizeof(sampleType));
int result = f->Read((void *) buffer, (int) (len * sizeof(sampleType)));
wxASSERT(result == (int) (len * sizeof(sampleType)));
f->Close();
}示例2: Read
void WaveTrack::Read(sampleType * buffer, WaveBlock * b,
sampleCount start, sampleCount len)
{
wxASSERT(b);
wxASSERT(start >= 0);
wxASSERT(start + len <= b->len);
BlockFile *f = b->f;
bool opened = f->OpenReadData();
wxASSERT(opened);
f->SeekTo(totalHeaderLen + (start * sizeof(sampleType)));
int result = f->Read((void *) buffer, (int) (len * sizeof(sampleType)));
if (result != (int) (len * sizeof(sampleType))) {
printf("Expected to read %d bytes, got %d bytes.\n",
len * sizeof(sampleType), result);
}
wxASSERT(result == (int) (len * sizeof(sampleType)));
f->Close();
