special prefixes means that there is no way to directly reference a C
identifier that starts with "struct_", "union_", "enum_", or
"sizeof_", such as a function named "struct_function".
A workaround is to use a "#define" in the preamble, as in
"#define c_struct_function struct_function" and then in the
Go code refer to "C.c_struct_function".

A C function may be declared in the Go file with a parameter type of
