fprintf()                Write Formatted Data to Stream

 #include   <stdio.h>

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



    fprintf() formats and prints a series of characters and values to the
    output 'stream'.  If there are any 'arguments', they are converted
    and output according to the specification in 'format- string'.

    Except for the capability to specify the stream to print to,
    fprintf() is identical to printf().  The format string and arguments
    of fprintf are identical to those of printf(); see printf() for a
    complete description of the format string and arguments.

    Returns:    The number of characters printed.

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

    The following statements open a file and write formatted data to it.

         #include <stdio.h>

         FILE *stream;
         char *name = "BOB SMITH";
         int enum = 1;
         char sex = 'M';

         main()
         {
             if ((stream = fopen("results.dat","w+")) != NULL) {
                     fprintf(stream,"%d, %s, %c\n", enum, name, sex);
             }
         }
