 fscanf()                Read Formatted Data from Screen

 #include   <stdio.h>

 int        fscanf(stream,format-string[,argument,...]);
 FILE       *stream;                     Pointer to file structure
 const char *format-string;              Format-control string

    fscanf() reads data from the current position of 'stream' into the
    locations given by 'arguments'. 'format-string' determines how the
    input fields are to be interpreted.  Each argument must be a pointer
    to a variable with a type that corresponds to a type specifier in
    'format-string'.  'format-string' is identical to that used by the
    scanf() function; see scanf() for a complete description of
    'format-string' and arguments.

       Returns:     The number of fields that were successfully converted
                    and assigned. A return value of EOF means an attempt
                    was made to read at end-of-file. A return value of 0
                    means no fields were assigned.

   -------------------------------- Example ---------------------------------

    This example opens a new file, places data in it, uses fscanf() to
    retrieve data from the stream, prints the data out, and closes the
    file.

           #include <stdio.h>

           FILE *stream;
           int num;
           char name[15];

           main()
           {
               if ((stream = fopen("scantest","w+")) != NULL) {
                  fputs("001Smith,J 002Jones,B",stream);
                  rewind(stream);
                  do
                      {
                      fscanf(stream,"%3d%15s",&num,name);
                      printf("found: %s (%d).\n",name,num);
                  } while (!feof(stream));
                fclose(stream);
                }
           }
