for (i = 0; i < num; i++) {
sprintf(filename,"%s_%04d.bin",file_head,i);
fid[i] = fopen(filename,"rb");
if (fid[i] == NULL) {log_file_loading_error("file", filename); free_fid(fid, num); free(pq); return 1;}
fread(&new, sizeof(CREC), 1, fid[i]);
new.id = i;
insert(pq,new,i+1);
}
when the content in "filename" is empty, the CREC new will computer twice。
let's see the corpus has only the following words:
"training the vectors can be speeded up by increasing the training parallelism to match the number of physical CPU cores available"
there will generate two bin files, and one of files is empty.
