Function Documentation

log_6addr()

void log_6addr

(

const uip_ipaddr_t *

ipaddr

)

Logs an IPv6 address.

Parameters

ipaddr

The IPv6 address

log_6addr_compact()

void log_6addr_compact

(

const uip_ipaddr_t *

ipaddr

)

Logs an IPv6 address with a compact format.

Parameters

ipaddr

The IPv6 address

Definition at line 123 of file log.c.

References ipaddr, and log_6addr_compact_snprint().

log_6addr_compact_snprint()

int log_6addr_compact_snprint	(	char *	buf,
		size_t	size,
		const uip_ipaddr_t *	ipaddr )

Write at most size - 1 characters of the IP address to the output string, in a compact representation.

The output is always null-terminated, unless size is 0.

Parameters

buf	A pointer to an output string with at least size bytes.
size	The max number of characters to write to the output string.
ipaddr	A pointer to a uip_ipaddr_t that will be printed with printf().

log_bytes()

void log_bytes	(	const void *	data,
		size_t	length )

Logs a byte array as hex characters.

Parameters

data	The byte array
length	The length of the byte array

Definition at line 167 of file log.c.

log_get_level()

int log_get_level

(

const char *

module

)

Returns the current log level.

Parameters

module

The target module string descriptor

Returns

The current log level

Definition at line 208 of file log.c.

log_level_to_str()

const char * log_level_to_str

(

int

level

)

Returns a textual description of a log level.

Parameters

level

log level

Returns

The textual description

Definition at line 224 of file log.c.

log_lladdr()

void log_lladdr

(

const linkaddr_t *

lladdr

)

Logs a link-layer address.

Parameters

lladdr

The link-layer address

Definition at line 132 of file log.c.

log_lladdr_compact()

void log_lladdr_compact

(

const linkaddr_t *

lladdr

)

Logs a link-layer address with a compact format.

Parameters

lladdr

The link-layer address

log_set_level()

void log_set_level	(	const char *	module,
		int	level )

Sets a log level at run-time.

Logs are included in the firmware via the compile-time flags in log-conf.h, but this allows to force lower log levels, system-wide.

Parameters

module	The target module string descriptor
level	The log level

Definition at line 193 of file log.c.

log_string()

void log_string	(	const char *	text,
		size_t	length )

Logs a string that has a length specified, but might not be zero-terminated.

Parameters

text	The string
length	The max length of the string
