fscanf

#include <stdio.h>

int fscanf  (
    FILE*       stream,    /* file stream to read from */
    const char* fmtstr,    /* format string            */
    ...);                  /* additional arguments     */

The function fscanf reads values from a data stream and stores them with the specified format to a variable. The parameter stream is a file pointer defining the data stream to read. The parameter fmtstr is a character pointer defining the formatting string. The parameters additional arguments store the data according to the format string fmtstr. Each argument must be a pointer to a variable corresponding to the type defined in fmtstr.
