Type Alias riot_sys::shell_command_handler_t

pub type shell_command_handler_t = Option<unsafe extern "C" fn(argc: c_int, argv: *mut *mut c_char) -> c_int>;

@brief Prototype of a shell callback handler. @details The functions supplied to shell_run() must use this signature. It is designed to mimic the function signature of main(). For this reason, the argument list is terminated with a NULL, i.e argv[argc] == NULL (which is an ANSI-C requirement, and a detail that newlib’s getopt() implementation relies on). The function name is passed in argv[0].

             Escape sequences are removed before the function is called.

             The called function may edit `argv` and the contained strings,
             but it must be taken care of not to leave the boundaries of the array.
             This functionality is another property that many `getopt()`
             implementations rely on to provide their so-called "permute"
             feature extension.

@param[in] argc Number of arguments supplied to the function invocation. @param[in] argv The supplied argument list.

@return 0 on success @return Anything else on failure
