I need to read Vision file from .NET core on Linux system. I see there are Vision APIs and I can use them. I have only a problem: If I open a file in read-only mode, all read are with the "no lock" clause (as told in the documentation) If I open a file in a read-write mode, I need to specify if I want the lock (default) of if I want the no-lock The documentation says: Records read from a file open for I/O are automatically locked unless the external variable f_no_lock is set to a non-zero value first But how can I set this variable if I don't find any call in the library to set it? Can you provide any C# example for set/unset it?

Vision api - Read no lock

I need to read Vision file from .NET core on Linux system.

I see there are Vision APIs and I can use them.

I have only a problem:

If I open a file in read-only mode, all read are with the "no lock" clause (as told in the documentation)
If I open a file in a read-write mode, I need to specify if I want the lock (default) of if I want the no-lock

The documentation says:

Records read from a file open for I/O are automatically locked unless the external variable f_no_lock is set to a non-zero value first

But how can I set this variable if I don't find any call in the library to set it?

Can you provide any C# example for set/unset it?
