Question

I have a struct and I want to copy the elements in the outfname of orig to the outfname of dest. How can I do this?

typedef struct {
    char outfname[256];
} sudoku_t;

void sudoku_copy(sudoku_t* orig,sudoku_t* dest){
}

Thanks.

Answer 1

void sudoku_copy(sudoku_t* orig, sudoku_t* dest)
{
    *dest = *orig;
}

just use the assignment operator.

As a side-note I suggest you to use dest as the first parameter in your function to align with the C convention used by functions like memcpy and strcpy.
