Hi,

I am trying to create a file and put some content in
it, this is what i am doing...

__IMPORT__( "chrome://mozlib/content/lib/js/io/file/",
"file_instantiator.js" );
var IOFile = new IO_file_fileInstantiator();
IOFile.set_handle("Phoenix\test.txt");
IOFile.setOut("test");
IOFile.set_handle();

i've tried giving path in various ways like c:\\path,
chrome://path etc... but i am getting this error:

[Exception... "Component returned failure code:
0x80520001 (NS_ERROR_FILE_UNRECOGNIZED_PATH)
[nsILocalFile.initWithPath]" nsresult: "0x80520001
(NS_ERROR_FILE_UNRECOGNIZED_PATH)" location: "JS frame
::
chrome://mozlib/content/lib/js/io/file/instantiator.js
:: anonymous :: line 72" data: no]

Please guide me to the correct way of doing this... thanks!

IO_file_fileInstantiator::setHandle method arguments are:

1. integer constant: file type (directory or file) -- use 
IOFile.K.DIR_INSTANCE (1) for a directory and IOFile.K.FILE_INSTANCE (0) 
for a file;

2. string: local file system absolute path or chrome path (if the file 
is located in a chrome registered package) -- omitted to close the file 
handle;

3. integer: file permissions code (ala Unix) -- optional.

Your call raises an exception because the 1st (mandatory) argument is 
missing.

Have a look at setHandle method code in:
chrome://mozlib/content/lib/js/io/file/instantiator.js at line 58
