Prototype missing?

Re: Prototype missing?

The reason to introduce it is a very technical one:

Clipper never distinguished between constant and non constant strings. And it was a big missing, as a constant string can never be overwritten because that will generate a GPF. Harbour perfectly distinguishes between those different types of strings :-)

Thats why I tell you that Harbour is so good: its technical level is much higher and complete than the one implemented originally by Clipper.

Thats why Harbour is the real Clipper successor :-)

Yes, I know. But still I can't use a tool driven by a group of developers that I don't like.

I fully understand what you mean... :-)

Anyhow, we are technicians, and that means that many times we have to make desitions based on technical facts instead of based on personal preferences.

Yes, and the technical facts are that Harbour developers broke the compatibility too many times in the past for ununderstandable reasons. And we need of a stable product.

Enrico,

yes, I agree with you. There is always a price to pay... :-)

This is the xHarbour's prototype of hb_parc():

Code: Select all  Expand view
const char * hb_parc( int iParam, ... )


So it seems to return a const char *, just like hb_parvc() is supposed to do.

What am I missing?

And what about this?

Anyway, it won't solve all the problems. As an example, I still see CLIPPER FUNCNAME( PARAMS ) in some places.

Enrico,

That is kept for Clipper backwards compatibility only. We should use HB_FUNC( FUNCNAME ) instead.

So we can change all the remaining CLIPPER FUNCNAME( PARAMS )?

Did you see the other message of mine?

Enrico,

Yes, we should use HB_FUNC( ... ) only

I have compared the code of hb_parc() and hb_parvc() and it seems as they are the same except that hb_parc() does not accept the optional parameters. So the argument for constant and non constant seems useless... :-S

So, can we use hb_parc() instead of hb_parvc()? It's currently used in only 6 sources.

Enrico,

Only in those calls where it uses just one parameter

Why? Anyway, all the calls uses two parameters.

Because harbour's hb_parc() just accepts one parameter
