VMS Help CC, Run-time functions, fprintf  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  Performs formatted output to a specified file.

  Syntax:

       #include <stdio.h>

       int fprintf(FILE *file_pointer, const char
                   *format_string,...);

  The ...  represents optional expressions whose resultant types
  correspond to conversion specifications given in the format_string.
  If no conversion specifications are given, you can omit the output
  sources.  Otherwise, the function calls must have exactly as many
  output sources as there are conversion specifications, and the
  conversion specifications must match the types of the output
  sources.  Conversion specifications are matched to output sources
  in left-to-right order.

  The format string for the output of information can contain two
  kinds of items:

   o  Ordinary characters, which are copied to the output.

   o  Conversion specifications, each of which causes the conversion
      of a corresponding output source to a character string in a
      particular format.  Conversion specifications are matched to
      output sources in left-to-right order.

 A conversion specification consists of a % (or a %n$), followed by
 one or more optional characters, and concluding with a conversion
 specifier.
