Re: [Vala] Insert code C in Vala

[Frederik <scumm_fredo gmx net>]

Hi,

you can't embed C code directly into Vala code, but you can easily
call C functions from Vala by using the "extern" keyword:

-- a.vala ---------------------------------------------------

extern void this_is_a_c_function(int i, double d, string s);

void main() {
        print("This is Vala code\n");
        this_is_a_c_function(42, 3.14, "test");
}

-- b.c -----------------------------------------------------

#include <stdio.h>

void this_is_a_c_function(int i, double d, const char *s)
{
        puts("This is C code");
        printf("i: %d, d: %g, s: %s\n", i, d, s);
}

------------------------------------------------------------

$ valac -o test a.vala b.c
$ ./test
This is Vala code
This is C code
i: 42, d: 3.14, s: test



Best regards,

Frederik
