how to pass a string to python-wamr ?

[Huangxiaoze]

Hi, all

I wanted to call a C function as below in wasm

void hello(char *name) { printf("Hello, %s\n", name); }

My question is how can I invoke the hello function with wasm-c-api?

I would appreciate it if you can answer my question.

There's an example called callback_chain in the samples directory that I believe meets your needs.

In callback_chain.c, there's a function named log(), and callback_chain.wat will call this function to display the names of the currently executing Wasm functions.
