structure members outside main

ive been trying to solve this now for at least 2 hours.

Code:

---


struct sizes
{
    int e_size;
};

struct sizes headersizes;

headersizes.e_size = sizeof(struct ethhdr);

....
int main...

---

gcc tells me that there is a parse error before '.'
in this line

Code:

---

headersizes.e_size = sizeof(struct ethhdr);

---

why is this happening? cant i declare structure members as globals? or outside of a function?

thanks

You can declare a structure-variable outside a function, but you can not initialise a structure-variable outside a function in this way. But you can initialise a structure-variable during declaring, the same way you would do with other type of variables.

Code:

---

// This would initialise the struct member e_size to 1
struct sizes headersizes = {1};

---

in what way can i initialise it?
or isnt it possible?

I edited my post above just before your second post. :)

;) thanks

i appreciate your help very much! little help for big project :D

struct sizes
{
int e_size;
};

struct sizes headersizes = {(int)sizeof(struct ethhdr)};

...
int main...


****Edit****
Looks like you sorted it out while I was posting. :)
