Read command-line argument data.
args_get() function is used to read the command-line argument data provided to the WebAssembly module. The sizes of the buffers should match the values returned by the
;;; passed to the program by the user. ;;; and may even be a fixed string. Subsequent arguments are the arguments ;;; program. This need not be a usable filesystem path or even file name, ;;; The first argument should be a string containing the "name" of the ;;; ;;; Each argument is expected to be `\0` terminated. ;;; ;;; The size of the array should match that returned by `args_sizes_get`. ;;; ;;; Read command-line argument data. (@interface func (export "args_get") (param $argv (@witx pointer (@witx pointer u8))) (param $argv_buf (@witx pointer u8)) (result $error (expected (error $errno))) )
ctx: A mutable reference to the function environment.
argv: A WebAssembly pointer to a buffer where the argument pointers will be written.
argv_buf: A WebAssembly pointer to a buffer where the argument string data will be written.
The function returns an
Errno value indicating the success or failure of the operation.
This function has been instrumented with debug-level logging. It will log the following information:
args: The command-line arguments in the WebAssembly module.
Please make sure the logging configuration is properly set up to capture the desired logs.
args_get() function reads the command-line argument data provided to the WebAssembly module. The argument pointers and string data are written to the specified buffers. The actual data is retrieved from the WebAssembly module's state.
