Public access to Argv0__[] [message #56628]

Is it possible to make extern char Argv0__[] publicly visible?
I need it to initialize third-party code in a way similar to the way gtk_init is doing this.

TIA

Just to be sure: You need the value of argv[0] of main, right? (the name of app)

Something like

String GetArgv0();

(things are complicated as Argv0 is POSIX specific...)

Yes. Exactly.

It is coming from main(int argc, char **argv) ...
A note from the API that I'm using:

Special consideration is required for argv[0]. On Unix, this argument passes the part of the command line that is used to locate the executable. Prolog uses this to find the file holding the running executable. The Windows version uses this to find a module of the running executable. If the specified module cannot be found, it tries the module libswipl.dll, containing the Prolog runtime kernel.
