Just a note that I can't seem to fix the problem in Ada example 17 (stripchart demo) wherein all of the legend strings appear on the plot identical to the fourth one. I've tried a lot of things and at this point I'm afraid it will have to be a "known issue."
The crux is matching e.g. this declaration in x17c.c: const char *legline[4]. I suppose this is a pointer to a four-element array of pointers to char which are to be interpreted as strings, probably with null terminators. (How does one know for sure?) This concept is reinforced by the documentation on plstripc. This is the current structure in the Ada bindings--a four-element array of pointers to null-terminated strings. I don't understand what the const in the above declaration does. I would think that it would cause the declared thing to be read-only, acquiring its values in the declaration itself, but it is in fact assigned to later in the program. In case I didn't interpret this C thing correctly, I also tried passing an array of strings (rather than an array of pointers to strings). This resulted in strlen, called from plstrdup, called from c_plstripc, either segfaulting or attempting to execute an invalid address. (How can such a basic and important core C function behave so badly, no matter what I passed it?)
