Detailed Description

WPA Supplicant / Control interface (shared code for all backends)

Function Documentation

char* wpa_supplicant_ctrl_iface_process	(	struct wpa_supplicant *	wpa_s,
		char *	buf,
		size_t *	resp_len
	)

Process ctrl_iface command.

Parameters

wpa_s	Pointer to wpa_supplicant data
buf	Received command buffer (nul terminated string)
resp_len	Variable to be set to the response length

Returns

Response (*resp_len bytes) or NULL on failure

Control interface backends call this function when receiving a message that they do not process internally, i.e., anything else than ATTACH, DETACH, and LEVEL. The return response value is then sent to the external program that sent the command. Caller is responsible for freeing the buffer after this. If NULL is returned, *resp_len can be set to two special values: 1 = send "FAIL\n" response, 2 = send "OK\n" response. If *resp_len has any other value, no response is sent.

char* wpa_supplicant_global_ctrl_iface_process	(	struct wpa_global *	global,
		char *	buf,
		size_t *	resp_len
	)

Process global ctrl_iface command.

Parameters

global	Pointer to global data from wpa_supplicant_init()
buf	Received command buffer (nul terminated string)
resp_len	Variable to be set to the response length

Returns

Response (*resp_len bytes) or NULL on failure

Control interface backends call this function when receiving a message from the global ctrl_iface connection. The return response value is then sent to the external program that sent the command. Caller is responsible for freeing the buffer after this. If NULL is returned, *resp_len can be set to two special values: 1 = send "FAIL\n" response, 2 = send "OK\n" response. If *resp_len has any other value, no response is sent.
