Hi,

Any pointers as to how to do this? Cheers, -Harry
Use cprefix= - maybe you also need to set cname=int in order to have
Vala know what to call the type of the values.
Yes! Thanks, that worked a charm.
Next stumbling block found:
when opening a file, sf_open(...) is called. To close the file,
sf_close(file) must be called.
[CCode (cheader_filename=sndfile.h,cname =SNDFILE)]
class Sndfile
{
[CCode (cname=sf_open, free_function=sf_close)]
public Sndfile(string path, FileMode mode, out Info sf_info );
}
free_function should be set on the class, not the constructor. Valac
should probably warn on unreconized annotations.
btw, your class should be compact.
HTH,
Abderrahim

[Vala] Graphic toolkits for Vala?
Hello, the last days i was fighting with some linux diagram editors (such as dia, umbrello, argouml...). And these programs don't cover my needs. At the end i thought may be i could make a program to help me to create beautiful diagrams.. but never i made a program that works with editable graphic elements. ¿Whic libraries should i use? (Probably i'll program it with Vala) I thought in clutter and/or cairo, but i don't know if these libraries do that i think they do . Thanks in advance -- - Per la llibertat del coneixement - - Per la llibertat de la ment... - ___ vala-list mailing list vala-list@gnome.org http://mail.gnome.org/mailman/listinfo/vala-list
[Vala] how to access the length attribute of multi dimensional arrays?
So if I pass a matrix to a function (or any multidimensional array), I can
only seem to access the .length attribute of the first dimension. Is there a
way to access the .length attributes of the other dimensions of the array?
public Something(int[,] arr)
{
_n_rows = arr.length;
_n_cols = arr[0, ].length; // no compile :(
}
In the example above, I can't seem to find a way to find out how many
columns are in my matrix.

Re: [Vala] how to access the length attribute of multi dimensional arrays?
Hey,
I've no experience with Multi-Dimensional arrays in Vala, but I can quote a
tutorial:
http://live.gnome.org/Vala/ValaForJavaProgrammers#Arrays
It provides the basics of Vala for Java programmers (me.. in college ;-(
but also has a piece that might be of intrest to you.
