示例1: fclose
Ps2WriteFile::~Ps2WriteFile(void) {
if ((_fd >= 0) && (_bytesInCache)) {
fio.write(_fd, _cacheBuf, _bytesInCache);
int wrRes = fio.sync(_fd);
if (wrRes != (int)_bytesInCache) // too late to return an error
printf("Cache flush on fclose(): Unable to write %d cached bytes to mc, only %d bytes written\n", _bytesInCache, wrRes);
}
if (_fd >= 0)
fio.close(_fd);
free(_cacheBuf);
}示例2:
Ps2File::~Ps2File() {
uint32 w;
if (_fd >= 0) {
if (_mode != O_RDONLY) {
fio.seek(_fd, 0, SEEK_SET);
fio.write(_fd, _cacheBuf, _filePos);

dbg_printf("flushed wbuf: %x of %x\n", w, _filePos);
}
fio.close(_fd);
uint32 r = fio.sync(_fd);
dbg_printf("close [%d] - sync'd = %d\n", _fd, r);
}
