[Hamlib-developer] Kylix binding for Hamlib

[Francois R. <fgr...@su...>]

Hello All,

I committed a binding for Borland's Kylix to the CVS.

Included in the tests/ directory is a small demo/test program.
It can select a rigs and open a very primative frequency display
dialog box.  Will improve later..


One problem I found while testing the binding was that there is no
way to verify that a non-null rig pointer is pointing to a valid 
rig structure.  During testing I solved this by adding a magic 
numbers to the rig structure.

Thus instead of

	if (!rig || !rig->caps) {
		return -RIG_EINVAL;
	}

we also check the magic numbers.

	if (!rig || rig->magic != RIG_MAGIC) {
		return -RIG_EINVAL;
	}
	if (!rig->caps || rig->caps->magic != RIG_MAGIC_CAPS) {
		return -RIG_EINVAL;
	}

Should we add magic numbers to the rig structures?  I can submit 
a patch if there is a need.
