Function Documentation

static bs_status bsmod_hand_cleanup ( void ) [static]

Cleanup the hand module by destroying its memory pool

Definition at line 107 of file bsmod_hand.c.

References BS_OK, companion, and mempool.

static bs_status bsmod_hand_handle_service	(	const bs_service_request *	request,
		bs_service_response **	response,
		void *	extra
	)			`[static]`

Service handling routine. Since the hand module doesn't offer any services, it will return BS_NO_SERVICE on all occasions.

Definition at line 191 of file bsmod_hand.c.

References BS_NO_SERVICE, BS_OK, companion, bs_part_instance::data, bs_service_request::input, make_answer(), bs_service_request::operation, bs_message_instance::parts, remove_temp_file(), streq(), and wait_for_answer().

Here is the call graph for this function:

static bs_status bsmod_hand_init ( void ) [static]

Initialize the hand module by creating a UUID for it.

Definition at line 75 of file bsmod_hand.c.

References BS_ERROR, BS_OK, companion, and mempool.

static bs_service_response* create_status_response	(	const bs_service_request *	request,
		bs_status	status,
		char *	message
	)			`[static]`

Create a correct service response message for all the operations in the module.

Parameters:

	request	The original request issued
	status	The status code part of the message
	message	The message part of the return message

Returns:: Service response structure or NULL if there was an error.

Here is the call graph for this function:

static bs_service_response* make_answer ( const bs_service_request * request ) [static]

Reads the produced answer file and creates an appropriate status response. Aftwerwards, the answer file is deleted.

Definition at line 160 of file bsmod_hand.c.

References BS_OK, create_status_response(), len(), mempool, read_file_into_buf(), remove_temp_file(), and runtestsuite::rv.

Here is the call graph for this function:

static void remove_temp_file ( void ) [static]

The companion java program leaves a temporary file called answer.tmp. Because this file is overwritten each time a request is made, it should be deleted before making the request.

Definition at line 98 of file bsmod_hand.c.

Referenced by bsmod_hand_handle_service(), bsmod_keystroke_handle_service(), and make_answer().

static void wait_for_answer ( void ) [static]

Keep waiting until the temporary file shows up.
