What is wrong with this?

[JustSomeGuy]

typedef struct
{
unsigned char item_type;
unsigned char res;
unsigned short item_len;
} item_type;

if (item.item_type != 0x30)

Gives the error:
rq.h(46) : error C2274: 'function-style cast' : illegal as right side of '.'
operator

VC++ 6.0

typedef struct
{
unsigned char item_type;
unsigned char res;
unsigned short item_len;
} item_type;

if (item.item_type != 0x30)

Gives the error:
rq.h(46) : error C2274: 'function-style cast' : illegal as right side of '.'
operator

WTF is 'item'?

typedef struct

This is unnecessary in C++.

{
unsigned char item_type;
unsigned char res;
unsigned short item_len;
} item_type;

You typdefed the struct to the same name as one of the members? What
exactly are you trying to do here?

Your compiler may be confused because you have declared
"item_type" as a typedef and also as a member. Try changing
the names:

struct item_struct
{
unsigned char item_ID;
unsigned char res;
unsigned short item_len;
};
Note that in C++, there is no "typedef" required. Also, if you
give us more information about the "big picture", we could tell
you a better method of design that doesn't need to know about
"item_type" or "item_ID" field.

Sorry... gcc liked this vc++ didn't.
because item_type being the type is the same name as one of its members.
