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.

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.
