How does one use "FFlattenPath()" ?

[KevinW]

Hi,

I am programming a DLL for use with a Code Library VI.

One procedure in this DLL gets a LabVIEW Path as a parameter.

So far so good:

FNamePtr(path, strptr) gives the proper filename, etc. FExists(path) reports the file exists, and is a file, as expected.

However: I need the full path and filename written to a conventional C-string, so that this can be passed to another function.

I think FFlattenPath() is meant to do this, but it does not work.

I have:

...
fprintf(file, "len = %d\n", FFlattenPath(filepath, 0));
FFlattenPath(filepath, filenameP);
PToCStr(filenameP, filenameC);
fprintf(file, "file = %s\n", filenameC);
...

Two problems:

- the debugging text "len = %d" does not show the correct leng
th.

- the filename written to the debug file is also very incorrect.

How is one supposed to use this function?

Thanks,

Kevin

Kevin,

I'm not clear on your question, but if you are trying to input a path into C as a string, just use the path to string conversion function in LabVIEW to convert the path to a string.

If your question is on how to convert a path to a string in C in your DLL, I can't help you there, as I'm not yet familiar with C.

So, if you are trying to get a path into your DLL, you have the answer, otherwise...

Okay, I read it again, and again, and again....

It seems you are trying to read a Path from LabVIEW and convert it to a string in C.

Just convert it to a string in LabVIEW, and operate on it in C as a string.

I would like to get information about the file as well - permissions, etc. I wanted to the use C-functions such as FGetInfo() [I think its called - not at a LabVIEW station now] on the Path.

I could pass both the path AND the converted string to my procedure, but thats not very pretty.
