fwrite_stringfwrite_stringFwriteStringFwriteString (Operator)

Name

fwrite_stringfwrite_stringFwriteStringFwriteString — Write values in a file.

Signature

fwrite_string( : : FileHandle, String : )

The operator fwrite_stringfwrite_stringFwriteStringFwriteStringFwriteString puts out a string or numbers on the output file defined by the handle FileHandleFileHandleFileHandleFileHandlefileHandle. The output file must be opened in ASCII format by the operator open_fileopen_fileOpenFileOpenFileOpenFile. The values to be put out on the file are set in the parameter StringStringStringStringstringVal.

The call set_system(::'flush_file', <boolean-value>:)set_system("flush_file", <boolean-value>)SetSystem("flush_file", <boolean-value>)SetSystem("flush_file", <boolean-value>)SetSystem("flush_file", <boolean-value>) determines whether the output characters are put out directly on the output medium. If the value 'flush_file'"flush_file""flush_file""flush_file""flush_file" is set to 'false'"false""false""false""false", the characters (especially in case of screen output) show up only after the operator fnew_linefnew_lineFnewLineFnewLineFnewLine is called.

Strings as well as whole numbers and floating point numbers can be used as arguments. If more than one value serves as input, the values are put out consecutively without blanks.

Attention

The maximum string length is 1024 character (including the end of string character).

* results in the following output:
* 'text with numbers:5 and 1.00000'

Example (C)

   fwrite_string(FileHandle,"text with numbers: ") ;
   fwrite_string(FileHandle,"5") ;
   fwrite_string(FileHandle," and ") ;
   fwrite_string(FileHandle,"1.0") ;
/* results in the following output:       */
/*    'text with numbers: 5 and 1.00000'   */

/* Tupel Version */
  int  i;
  double d;
  Htuple Tuple ;

  create_tuple(&Tuple,4) ;
  i = 5 ;
  d = 10.0 ;
  set_s(Tuple,"text with numbers: ",0) ;
  set_i(Tuple,i,1) ;
  set_s(Tuple," and ",2) ;
  set_d(Tuple,d,3) ;
  T_fwrite_string(FileHandle,HilfsTuple) ;
