// Save CvRect rect to ‘rect.yml‘
CvFileStorage *fs = cvOpenFileStorage("rect.yml", 0, CV_STORAGE_WRITE);
if (!fs) {
    fprintf(stderr, "Could not open file ..\n");
    return;
}
cvStartWriteStruct(fs, "rect", CV_NODE_SEQ | CV_NODE_FLOW);
cvWriteInt(fs, 0, rect.x); cvWriteInt(fs, 0, rect.y); cvWriteInt(fs, 0, rect.width); cvWriteInt(fs, 0, rect.height);
cvEndWriteStruct(fs);
cvReleaseFileStorage(&fs);
