`fiprintf'--format output to file (integer only)

     #include <stdio.h>
     int fiprintf(FILE *FD, const char *FORMAT, ...);
`fiprintf' is a restricted version of `fprintf': it has the same
arguments and behavior, save that it cannot perform any floating-point
formatting--the `f', `g', `G', `e', and `F' type specifiers are not
`fiprintf' returns the number of bytes in the output string, save that
the concluding `NULL' is not counted.  `fiprintf' returns when the end
of the format string is encountered.  If an error occurs, `fiprintf'
returns `EOF'.
`fiprintf' is not required by ANSI C.
   Supporting OS subroutines required: `close', `fstat', `isatty',
`lseek', `read', `sbrk', `write'.
