Reading struct

[Anonymous]

Hello,

we have a struct, which we are using to read a header of a file.

So it looks like:

struct StructMyHeader {
    char            id[4];
    unsigned long   size;
    ...
}

struct MyHandle : MyParentHandle
{
    MyHandle() : MyParentHandle() {}
    ~MyHandle() {};

    QFile file;
    StructMyHeader myHeader;
};

bool readFile(...)
{
    ...
    file.read(reinterpret_cast<char*>(&myHeader), sizeof(StructMyHeader));
    ...
}

But if we do so, we got some hundreds warnings of Cppcheck because of unusedStructMember (we don't handle all values of header) and an uninitMemberVar hint in MyHandle. Is there a clean way to supress this warnings just for this struct without adding a cppcheck supressing hint to each member? I think a simple memset is not enough?

One way is to put StructMyHeader in a header file. This check only warns for structs declared in the non-included source file.

But it also feels like the check should somehow know that file.read will access all the struct members.
