error C2678
-
Ok, but even
flagis comming as function parameter, just like this:static void SomeFunction(level1* na, FILE_FLAGS flag)
{
....
na->flags |= ~flag;
....
}So, I guess I cannot give up FILE_FLAGS
enum... don't I ?Change this parameter to be
static void SomeFunction(level1* na, int flag)
{ -
I am not get something, so forgive me. I have moved those
enumvalues as#defines, but of course, now I get error fromstruct: doesn't know who isFILE_FLAGS flags;fromlevel1struct./*

Add this line somewhere before the first reference to
FILE_FLAGS:typedef int FILE_FLAGS;

I encounter another error if I made these modifications:
data->com = na->flags & ATTR_IS_COMPRESSED; // <-- error C2059: syntax error : '='
(where data->com is
int) because nowATTR_IS_COMPRESSEDis#define, not part ofenum FILE_FLAGS...What is

because now
ATTR_IS_COMPRESSEDis#define, not part ofenum FILE_FLAGSThat is not the reason. I can only assume that you have done a partial change and some parts of your code are still incorrect. If you still have the FILE_FLAGS enum then it is going to cause problems. It would probably help if you showed all the code portions that are connected. It is difficult to be certain of the answers when looking at only a single line of code.

I still cannot see enough information. Please provide what I previously requested and reply to this message. Please do not email me personally.

The fact is like that: I have an error:
error C2059: syntax error : '='
the error is reported here:
data->com = na->flags & ATTR_IS_COMPRESSED;
where: data is a struct:
struct data
{
.....
int com;
...
};and na is
RECORD* na;
and RECORD is:
typedef struct {
....
....
int flags;
.....
}RECORD;and
ATTR_IS_COMPRESSED
is from here (from my modifications):
typedef int ATTR_FLAGS;
//typedef enum {
// ATTR_IS_COMPRESSED = 0x0001,
// ATTR_COMPRESSION_MASK = 0x00ff,
//}ATTR_FLAGS;#define ATTR_IS_COMPRESSED = 0x0001
#define ATTR_COMPRESSION_MASK = 0x00ff -

#define ATTR_COMPRESSION_MASK = 0x00ffNot sure why you posted all that back to front ... However there are a couple of simple mistakes:
#definestatements do not require an=sign. They should be#define ATTR_IS_COMPRESSED 0x0001
#define ATTR_COMPRESSION_MASK 0x00ffThe name
datarefers to a struct definition, not a variable. You need something like:typedef struct
{
.....
int com;
...
} DATA;DATA* data;
I am assuming that you actually assign the memory required for both structures at some point further on.
