Hi,
The _Generic keyword is a C11 feature that does not seem available in Intel compilers. It would allow better implementation of object-oriented code in C. Do you plan to support it in the next releases ?
typedef struct {
int size;
double *data;
} VectorDouble;
typedef struct {
int size;
int *data;
} VectorInt;
#define alloc(a, n) _Generic((a), VectorDouble: alloc_VectorDouble(&a, n), VectorInt: alloc_VectorInt(&a, n))
#define release(a) _Generic((a), VectorDouble: release_VectorDouble(a), VectorInt: release_VectorInt(a))
#define at(a, i) _Generic((a), VectorDouble: a.data)
void alloc_VectorDouble(VectorDouble *a, int n) {
a->data = (double*) malloc(n * sizeof(double));
}
void free_VectorDouble(VectorDouble a) {
free(a.data);
}
void alloc_VectorInt(VectorInt *a, int n) {
a->data = (int*) malloc(n * sizeof(int));
}
void free_VectorInt(VectorInt a) {
free(a.data);
}
int main (int argc, char const *argv[])
{
const int n = 8;
VectorDouble a;
VectorDouble b;
VectorDouble c;
alloc(a, n);
alloc(b, n);
alloc(c, n);
for(int j = 0; j < n; ++j)
{
at(a, j) = at(b, j) + at(c, j);
}
release(a);
release(b);
release(c);
return 0;
}
Best regards,
Francois
