Function Documentation

void hostapd_logger_register_cb

(

hostapd_logger_cb_func

func

)

Register callback function for hostapd_logger().

Parameters:

func

Callback function (NULL to unregister)

Definition at line 370 of file wpa_debug.c.

void wpa_debug_print_timestamp

(

void

)

Print timestamp for debug output.

This function prints a timestamp in seconds_from_1970.microsoconds format if debug output has been configured to include timestamps in debug messages.

Definition at line 37 of file wpa_debug.c.

Here is the call graph for this function:

void wpa_hexdump	(	int	level,
		const char *	title,
		const u8 *	buf,
		size_t	len
	)

conditional hex dump

Parameters:

	level	priority level (MSG_*) of the message
	title	title of for the message
	buf	data buffer to be dumped
	len	length of the buf

This function is used to print conditional debugging and error messages. The output may be directed to stdout, stderr, and/or syslog based on configuration. The contents of buf is printed out has hex dump.

Definition at line 168 of file wpa_debug.c.

void wpa_hexdump_ascii	(	int	level,
		const char *	title,
		const u8 *	buf,
		size_t	len
	)

conditional hex dump

Parameters:

	level	priority level (MSG_*) of the message
	title	title of for the message
	buf	data buffer to be dumped
	len	length of the buf

This function is used to print conditional debugging and error messages. The output may be directed to stdout, stderr, and/or syslog based on configuration. The contents of buf is printed out has hex dump with both the hex numbers and ASCII characters (for printable range) are shown. 16 bytes per line will be shown.

Definition at line 265 of file wpa_debug.c.

void wpa_hexdump_ascii_key	(	int	level,
		const char *	title,
		const u8 *	buf,
		size_t	len
	)

conditional hex dump, hide keys

Parameters:

	level	priority level (MSG_*) of the message
	title	title of for the message
	buf	data buffer to be dumped
	len	length of the buf

This function is used to print conditional debugging and error messages. The output may be directed to stdout, stderr, and/or syslog based on configuration. The contents of buf is printed out has hex dump with both the hex numbers and ASCII characters (for printable range) are shown. 16 bytes per line will be shown. This works like wpa_hexdump_ascii(), but by default, does not include secret keys (passwords, etc.) in debug output.

Definition at line 271 of file wpa_debug.c.

void wpa_hexdump_key	(	int	level,
		const char *	title,
		const u8 *	buf,
		size_t	len
	)

conditional hex dump, hide keys

Parameters:

	level	priority level (MSG_*) of the message
	title	title of for the message
	buf	data buffer to be dumped
	len	length of the buf

This function is used to print conditional debugging and error messages. The output may be directed to stdout, stderr, and/or syslog based on configuration. The contents of buf is printed out has hex dump. This works like wpa_hexdump(), but by default, does not include secret keys (passwords, etc.) in debug output.

Definition at line 174 of file wpa_debug.c.

void wpa_msg_register_cb

(

wpa_msg_cb_func

func

)

Register callback function for wpa_msg() messages.

Parameters:

func

Callback function (NULL to unregister)

Definition at line 313 of file wpa_debug.c.

void wpa_printf	(	int	level,
		char *	fmt,
			...
	)

conditional printf

Parameters:

	level	priority level (MSG_*) of the message
	fmt	printf format string, followed by optional arguments

This function is used to print conditional debugging and error messages. The output may be directed to stdout, stderr, and/or syslog based on configuration.

Note: New line '
' is added to the end of the text when printing to stdout.
