OpenFile(): Add flag #PB_File_NoCreate

[Sicro]

Opens a file for reading/writing or creates a new file if it does not exist.

It would be good if the command had a flag that could disable the creation of a new file.
If the file does not exist then #False should be returned.

Use

Code: Select all

If FileSize(path) > -1 ;only open the file if it already exists
    OpenFile(fileID, path) 
Endif

If there's a flag, PB needs to check if the file exists, anyway, so it's probably not even faster to have it as a flag, versus what you can already do with a single If

[Sicro]

Yes, there are always workarounds, but in my opinion the command should support that natively.

If the file does not exist then #False should be returned.

E.g. the name #PB_File_Existing would be more intuitive then.

File existing?
Yes --> #True
No --> #False

@Little John:
You mean it should work the other way around: Instead of disabling the creation of the file with the flag #PB_File_NoCreate, there should be a flag #PB_File_Existing that enables the creation?

No, I don't mean that. That would be a different feature request.

I mean: If Fred will implement what you are asking for, then the new flag shold be named e.g. #PB_File_Existing (short for #PB_Open_Only_An_Already_Existing_File) rather than #PB_File_NoCreate.

#PB_File_Existing (short for #PB_Open_Only_An_Already_Existing_File) rather than #PB_File_NoCreate

Okay, I'm fine with that, too.
