files. The C code must not modify the contents of the pointer returned
by _GoStringPtr. Note that the string contents may not have a trailing
NUL byte.

As Go doesn't have support for C's union type in the general case,
C's union types are represented as a Go byte array with the same length.

Go structs cannot embed fields with C types.

Go code cannot refer to zero-sized fields that occur at the end of
