C code: error: incompatible types in assignment

hedpe · 12-04-2006, 02:42 AM

Hey,

I am trying to fix an incompatible types in assignment error, and I can't quite figure it out.

Here is where the error comes from:

Code:

curr_cap_header->markings[curr_marking] = (u8) 0;

Here is the related code

Code:

void create_capability_header(char *buffer, unsigned short buffer_size);

struct iphdr *ip_header;
pubkey_token *token_key;
bcap_token_hdr *token_header;
secflow_capability *curr_cap_header;

struct udphdr *udp_header;

char *currpos;

void create_capability_header(char *buffer, unsigned short buffer_size) {
	int curr_marking;
	curr_cap_header = (secflow_capability *) currpos;
	curr_cap_header->id = 1;
	curr_cap_header->prioclass = 0;
	curr_cap_header->cur_router = 1;

	for(curr_marking=0; curr_marking < MAXPATHLEN; curr_marking++) {
		curr_cap_header->markings[curr_marking] = (u8) 0;
	}

	currpos = (char *)curr_cap_header + sizeof(secflow_capability);
}

Code:

typedef struct t_secflow_marking{
  u8 marking;
} secflow_marking;

typedef struct t_secflow_capability{
  u32 id;
  u16 prioclass;
  u16 cur_router;
  secflow_marking markings[MAXPATHLEN];
}secflow_capability;

I'd appreciate any help... thanks!

I dont see anything wrong here.
Just give me how u8 is type defined?

Shouldn't your code be:

Code:

curr_cap_header->markings[curr_marking].marking = (u8) 0;
