openfile

Purpose

Open output file stream.

Syntax

returnedOstream = openfile(path_str [, mode_str [, mode_str [, mode_str]]] )

returnedOstream - type: ostream
path_str - type: str

mode_str - type: str

Returns

Remarks

Zero to three mode strings selected from: 1) "app" = append; 2) "ate" = special C++ append; 3) "binary" = open in binary mode (text is default).

openfile is analogous to C++ open file function.

WARNING: Default mode is OVERWRITE, not APPEND. Unlike fileout(), does not create a global variable for the file stream.

In specifying file names, double slashes should be used. To specify output.txt use c:\\output.txt, not c:\output.txt.

Files should not be placed in the application's input folder since VisualText wipes out the files after each text analysis. For example, a file called blob.txt in the folder c:\\apps\input\\eg1.txt_log will get deleted each time the text gets analyzed.

Example

@CODE
G("file") = openfile("c:\\tmp.txt");
closefile(G("file"));
