[tfarina, 2013/09/11 19:39:25]

typedef should not be necessary here as we compile with C++ rather than C.

[tfarina, 2013/09/11 19:39:25]

I think this can be simply:

struct ErrorContext {
};

unless I'm missing something.

+    skiatest::Reporter *fReporter;
+    unsigned int *fIntPointer;
+} ErrorContext;

[tfarina, 2013/09/11 19:39:25]

this is creating a variable as far as I can see. Do you need this?

[mtklein, 2013/09/11 20:51:19]

Oh how I love C++ syntax!

typedef struct { ... } Foo;

makes a type Foo which is a struct, as if you'd written

struct Foo { ... };

on the other hand, visually similar

struct { ... } Foo;

makes a variable Foo whose type is an anonymous struct.

But, yeah, C++ generally would write

struct ErrorContext {
    skiatest::Reporter *fReporter;
    unsigned int *fIntPointer;
};
