I was looking at some code and I am trying to figure out what does the 770 mean on the following open statement?

fopen var_001 770 "%/ntelval.tmp

What does 770 do?

Thanks

I found the answer to my question.

unbaja creates random designations for stuff that is lost when it decompiles. atleast i think that's why.

so if i had a variable that was named BUTT, when decompiled it would give
it another designation

Probably more to do with the mode the file is created with. 770 = rwx to
both owner and group and no permissions to other.

well it's an undocumented feature then.

*FOPEN <int_var> <#> <"str" or str_var> FILE_IO.INC
args: handle access path_and_filename *------------------------------------------
This function opens or creates a disk file (path_and_filename) for read and/or write access. This function is the Baja equivalent of the standard C fopen() function. No file I/O operations can be performed on a file until it has been opened with this function. The 'handle' argument must be a defined integer variable name. The 'access' argument is the requested open access. The access flags (defined in FILE_IO.INC) are:

Access Flag Description
~~~~~~~~~~~ ~~~~~~~~~~~
O_RDONLY Read Only
O_WRONLY Write Only
O_RDWR Read and write
O_CREAT Create (create if doesn't exist)
O_APPEND Append (writes to end of file)
O_TRUNC Truncate (truncates file to 0 bytes automatically)
O_EXCL Exclusive (only open/create if file doesn't exist)
O_DENYNONE Deny None (shareable, for use with record locking)

It's the integer value of the programmer's specified file access. i.e. 770 is the combintaino of some of the O_* flags. It's documented.

I was guessing, it looked like a file mode. I never claimed to be an expert.

i'm not seeing any 770
so you are saying exclusive+truncation+create = 700 ?
i didnt know it could be used that way

You just add or bit-wise-or the value together.

so you are saying exclusive+truncation+create = 700 ?

Right.

i didnt know it could be used that way

Same as *nix permissions/mask values.

If I'm not mistakened, the 770 is base 8, or Octognal representation.
Just a FYI to the other poster....
