Macro Definition Documentation

LOG_ITEM_MAX

#define LOG_ITEM_MAX   64

Maximum number of key/value pairs in a log event.

May be changed or abolished later.

Typedef Documentation

log_item_iter

typedef struct _log_item_iter log_item_iter

Iterator over the key/value pairs of a log_line.

At present, only one iter may exist per log_line.

log_item_wellknown_key

typedef struct _log_item_wellknown_key log_item_wellknown_key

Pre-defined "well-known" keys, as opposed to ad hoc ones, for key/value pairs in logging.

log_line

typedef struct _log_line log_line

log_line ("log event")

Function Documentation

kr_line_item_set_with_key()

static log_item_data * kr_line_item_set_with_key ( log_line *  ll, log_item_type  t, const char *  k, uint32  alloc  )

static

Base for line_item_set[_with_key].

Stripped down version of that in log_builtins.cc.

kr_log_item_free()

static void kr_log_item_free ( log_item *  li )

static

Release any of key and value on a log-item that were dynamically allocated.

Parameters

li	log-item to release the payload of

kr_log_line_item_free_all()

static void kr_log_line_item_free_all ( log_line *  ll )

static

Release all log line items (key/value pairs) in log line ll.

This frees whichever keys and values were dynamically allocated.

Parameters

ll

log_line

log_item_wellknown_by_type()

static int log_item_wellknown_by_type ( log_item_type  t )

static

Check if we know about the item type.

log_label_from_prio()

static const char * log_label_from_prio ( int  prio )

static

Convenience function: Derive a log label ("error", "warning", "information") from a severity.

Parameters

prio	the severity/prio in question

Returns

a label corresponding to that priority.

Return values

System	for prio of SYSTEM_LEVEL
Error	for prio of ERROR_LEVEL
Warning	for prio of WARNING_LEVEL
Note	for prio of INFORMATION_LEVEL
