TianlongLiang c3e33a96ea Remove unused argument in wasm_runtime_lookup_function and refactor WASMModuleInstance (#3218 ) Remove the unused parameter `signature` from `wasm_runtime_lookup_function`. Refactor the layout of WASMModuleInstance structure: - move common data members `c_api_func_imports` and `cur_exec_env` from `WASMModuleInstanceExtraCommon` to `WASMModuleInstance` - In `WASMModuleInstance`, enlarge `reserved[3]` to `reserved[5]` in case that we need to add more fields in the future ps. https://github.com/bytecodealliance/wasm-micro-runtime/issues/2530 https://github.com/bytecodealliance/wasm-micro-runtime/issues/3202		2024-03-13 12:28:45 +08:00

README.md

The "basic" sample project

This sample demonstrates a few basic usages of embedding WAMR:

initialize runtime
load wasm app and instantiate the module
call wasm function and pass arguments
export native functions to the WASM apps
wasm function calls native function and pass arguments
deinitialize runtime

Build this sample

Execute the build.sh script then all binaries including wasm application files would be generated in 'out' directory.

$ ./build.sh

Run the sample

Enter the out directory.

$ cd ./out/
$
$ ./basic -f wasm-apps/testapp.wasm
calling into WASM function: generate_float
Native finished calling wasm function generate_float(), returned a float value: 102009.921875f
calling into WASM function: float_to_string
calling into native function: intToStr
calling into native function: get_pow
calling into native function: intToStr
Native finished calling wasm function: float_to_string, returned a formatted string: 102009.921

Or execute the run.sh script in samples/basic folder.

$ ./run.sh
