 // The CBIND macro is a convenient utility that abstracts away several steps in binding C functions with msgpack
 // serialization. It creates two separate functions:
 // 1. cname function: This decodes the input arguments from msgpack format, calls the target function,
 // and then encodes the return value back into msgpack format.
 // 2. cname##__schema function: This creates a JSON schema of the function's input arguments and return type.
