Many times we need to write data to the file when it is very disturbing, because the format of seven or eight slots, the readability is too poor,So we think that there is no function can be formatted from the file input and output, there is really.

In libcurl example HIPERFIFO.C, function FIFO_CB uses fscanf (FIFO InputStream,...) to read in a string.RV=FSCANF (G->input, "%1023s%n", S, &n);When the FIFO content producer sends-continuously with no interval, the FIFO_CB would lost the second URL.
