[Vala] trying vapi file for ngspice, segfaults

[Steven Vanden Branden <stevenvandenbrandenstift gmail com>]

hello,
seems like the mail got lost but anyway have read the answer on
mailarchive about the bool, got the vapi to compile but get an segment
fault error when i try to run the application so i would like to review
the vapi for the function that causes it:

#if __GNUC__ >= 4
    #define IMPEXP __attribute__ ((visibility ("default")))
    #define IMPEXPLOCAL  __attribute__ ((visibility ("hidden")))


IMPEXP
int  ngSpice_Init(SendChar* printfcn, SendStat* statfcn, ControlledExit*
ngexit, SendData* sdata, SendInitData* sinitdata, BGThreadRunning*
bgtrun, void* userData);

the arguments are almost all pointer to callback functions and these i
need to get in my vala program.

vapi code :

> [CCode (cname = "ngSpice_Init")]
>               public int init(out SendOutput* a,out SendSimulationStatus* b,out ControlledExit* c
>               , out SendVectorData* d, out SendInitializationData* e, out IsBackgroundThreadRunning* f, out 
> void * userData);
>               

the code in my vala class:

                public SendOutput* a;
                public SendSimulationStatus* b ;
                public ControlledExit* c;
                public SendVectorData* d;
                public SendInitializationData* e;
                public IsBackgroundThreadRunning* f;

ngspice.init(out a,out b,out c,out d,out e,out f,null);


i am compiling the ngspice library with debug symbols now to get a
working trace to see if this is a vapi error from me or a lib problem.

greetings and thanks for the assistance,
Steven

hello all, 

im trying to write a vapi file for the ngspiceshared header file and
library but i got a compile error about bool not defined in the c
compiler, any thoughts?

typedef struct vecvalues {
    char* name;        /* name of a specific vector */
    double creal;      /* actual data value */
    double cimag;      /* actual data value */
    bool is_scale;     /* if 'name' is the scale vector */
    bool is_complex;   /* if the data are complex numbers */
} vecvalues, *pvecvalues;

and the corresponding vapi file entry

[CCode (cname = "vecvalues", has_destroy_function = false,
has_copy_function = false, has_type_id = false)]
        
public struct VecValues {
                public string name;        /* name of a specific vector */
                public double creal;      /* actual data value */
                public double cimag;      /* actual data value */
                [CCode (cname = "is_scale")] 
                public bool isScale;     /* if 'name' is the scale vector */
                [CCode (cname = "is_complex")]
                public bool isComplex;   /* if the data are complex numbers */
}       //vecvalues, *pvecvalues;

Is the vapi for this correct?

greets,
