描述

算子 fnew_linefnew_lineFnewLineFnewLineFnewLinefnew_line writes a line break into the output file defined by the handle FileHandleFileHandleFileHandleFileHandlefileHandlefile_handle. The input file must have been opened with open_fileopen_fileOpenFileOpenFileOpenFileopen_file in text format. The call of fnew_linefnew_lineFnewLineFnewLineFnewLinefnew_line also empties possibly retained data from the output buffer into the file (see fwrite_stringfwrite_stringFwriteStringFwriteStringFwriteStringfwrite_string and 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>)set_system("flush_file", <boolean-value>)).

Which characters are written as line break depends on the operating system: under Windows the sequence '\r\n'"\r\n""\r\n""\r\n""\r\n""\r\n" (carriage return + line feed) is used as the standard line break, under Linux just '\n'"\n""\n""\n""\n""\n" (line feed).

执行信息

• 多线程类型：可重入（与非独占算子并行运行）。
• 多线程作用域：全局（可从任何线程调用）。
• 未采用并行化处理。

参数

  fwrite_string(FileHandle,'Good Morning')
  fnew_line(FileHandle)
  

  fwrite_string(FileHandle,"Good Morning");
  fnew_line(FileHandle);
  

  fwrite_string(FileHandle,'Good Morning')
  fnew_line(FileHandle)
  

  fwrite_string(FileHandle,'Good Morning')
  fnew_line(FileHandle)
  

  fwrite_string(FileHandle,'Good Morning')
  fnew_line(FileHandle)
  

结果

If an output file is open and it can be written to the file, the operator fnew_linefnew_lineFnewLineFnewLineFnewLinefnew_line 返回值 2 ( H_MSG_TRUE )。否则，将抛出异常。
