[Plplot-general] Bindings for Ada and a dumb C question

[<lan...@qw...>]

Hi list,

Sorry to bother with such a trivial question that should properly be  
asked elsewhere, but maybe you'll humor me.

I'm making some serious progress as a spare-time project in making  
Ada bindings for PLplot, and some of the examples are working well.  
Here's my dumb C question: If there is a C procedure such as

void plfoo(PLFLT *bar);

how does one tell if the parameter is intended to be a pointer to an  
array of PLFLT or whether it is simply a scalar (single number) PLFLT  
that is being passed by reference? Am I missing something here? Will  
I have to consult the API reference for each function to discover  
what is intended if it's not obvious otherwise?

Jerry (aka C idiot)
