  Write to file

Receives:
  int                      *guise          --- class of file:
                                           --- FFCROL,FFCSNP,FFCJNL,
                                           --- FFCXMT,FFCSCH,FFCDBG
  int                      *strid          --- frustrum strid
  int                      *nchars         --- num of chars/bytes to write >=0
  char                      buffer[]       --- buffer containing data to write

Returns:
  int                      *ifail          --- error code: FR_no_errors
                                           ---             FR_write_fail

Description:
  This function writes the contents of the buffer to file, starting at the
  current position of the file pointer. The file pointer is incremented by
  the number of characters or bytes written. In the case of a rollback file,
  Parasolid does not require the function to read beyond the actsiz
  limit which was returned by FFOPRB.
