TVMFFISafeCallType safe_call#: A C API compatible call with exception catching.

void *cpp_call#

A function pointer to an underlying cpp call.

The signature is the same as TVMFFISafeCallType except the return type is void, and the function throws exception directly instead of returning error code. We use void* here to avoid depending on c++ compiler.

This pointer should be set to NULL for functions that are not originally created in cpp.

Note

The caller must assume the same cpp exception catching abi when using this pointer. When used across FFI boundaries, always use safe_call.
