Expand description

Set native stack boundary to execution environment, if it is set, it will be used instead of getting the boundary with the platform layer API when calling wasm functions. This is useful for some fiber cases.

Note: unlike setting the boundary by runtime, this API doesn’t add the WASM_STACK_GUARD_SIZE(see comments in core/config.h) to the exec_env’s native_stack_boundary to reserve bytes to the native thread stack boundary, which is used to throw native stack overflow exception if the guard boundary is reached. Developer should ensure that enough guard bytes are kept.

@param exec_env the execution environment @param native_stack_boundary the user data to be set
