Detailed Description

RPM Logging facilities.

Typedef Documentation

rpmlogCallback

typedef int(* rpmlogCallback) (rpmlogRec rec, rpmlogCallbackData data)

Parameters

rec	rpmlog record
data	private callback data

Returns

flags to define further behavior: RPMLOG_DEFAULT to perform default logging, RPMLOG_EXIT to exit after processing, 0 to return after callback

Definition at line 133 of file rpmlog.h.

rpmlogFac

typedef enum rpmlogFac_e rpmlogFac

facility codes

rpmlogLvl

typedef enum rpmlogLvl_e rpmlogLvl

RPM Log levels.

priorities/facilities are encoded into a single 32-bit quantity, where the bottom 3 bits are the priority (0-7) and the top 28 bits are the facility (0-big number). Both the priorities and the facilities map roughly one-to-one to strings in the syslogd(8) source code. This mapping is included in this file.

priorities (these are ordered)

rpmlogRec

typedef struct rpmlogRec_s* rpmlogRec

Definition at line 107 of file rpmlog.h.

Enumeration Type Documentation

rpmlogFac_e

enum rpmlogFac_e

facility codes

Enumerator
RPMLOG_KERN	kernel messages
RPMLOG_USER	random user-level messages
RPMLOG_MAIL	mail system
RPMLOG_DAEMON	system daemons
RPMLOG_AUTH	security/authorization messages
RPMLOG_SYSLOG	messages generated internally by syslogd
RPMLOG_LPR	line printer subsystem
RPMLOG_NEWS	network news subsystem
RPMLOG_UUCP	UUCP subsystem
RPMLOG_CRON	clock daemon
RPMLOG_AUTHPRIV	security/authorization messages (private)
RPMLOG_FTP	ftp daemon
RPMLOG_LOCAL0	reserved for local use

rpmlogLvl_e

enum rpmlogLvl_e

RPM Log levels.

priorities/facilities are encoded into a single 32-bit quantity, where the bottom 3 bits are the priority (0-7) and the top 28 bits are the facility (0-big number). Both the priorities and the facilities map roughly one-to-one to strings in the syslogd(8) source code. This mapping is included in this file.

priorities (these are ordered)

Enumerator
RPMLOG_EMERG	system is unusable
RPMLOG_ALERT	action must be taken immediately
RPMLOG_CRIT	critical conditions
RPMLOG_ERR	error conditions
RPMLOG_WARNING	warning conditions
RPMLOG_NOTICE	normal but significant condition
RPMLOG_INFO	informational
RPMLOG_DEBUG	debug-level messages

Definition at line 29 of file rpmlog.h.

Function Documentation

rpmlog()

void rpmlog	(	int	code,
		const char *	fmt,
			...
	)

Generate a log message using FMT string and option arguments.

rpmlogClose()

void rpmlogClose

(

void

)

Close desriptor used to write to system logger.

Todo:

Implement.

rpmlogCode()

int rpmlogCode

(

void

)

Return error code from last rpmError() message.

Deprecated:

Perl-RPM needs, what's really needed is predictable, non-i18n encumbered, error text that can be retrieved through rpmlogMessage() and parsed IMHO.

Returns

code from last message

rpmlogGetNrecs()

int rpmlogGetNrecs

(

void

)

Return number of rpmError() ressages.

Returns

number of messages

rpmlogLevelPrefix()

const char* rpmlogLevelPrefix

(

rpmlogLvl

pri

)

Return translated prefix string (if any) given log level.

Parameters

pri	log priority

Returns

message prefix (or "" for none)

rpmlogMessage()

void const char* rpmlogMessage

(

void

)

Return text of last rpmError() message.

Returns

text of last message

rpmlogOpen()

void rpmlogOpen	(	const char *	ident,
		int	option,
		int	facility
	)

Open connection to system logger.

Todo:

Implement.

rpmlogPrint()

void rpmlogPrint

(

FILE *

f

)

Print all rpmError() messages.

Parameters

f	file handle (NULL uses stderr)

rpmlogRecMessage()

const char* rpmlogRecMessage

(

rpmlogRec

rec

)

Retrieve log message string from rpmlog record.

Parameters

rec	rpmlog record

Returns

log message

rpmlogRecPriority()

rpmlogLvl rpmlogRecPriority

(

rpmlogRec

rec

)

Retrieve log priority from rpmlog record.

Parameters

rec	rpmlog record

Returns

log priority

rpmlogSetCallback()

rpmlogCallback rpmlogSetCallback	(	rpmlogCallback	cb,
		rpmlogCallbackData	data
	)

Set rpmlog callback function.

Parameters

cb	rpmlog callback function
data	callback private (user) data

Returns

previous rpmlog callback function

rpmlogSetFile()

FILE* rpmlogSetFile

(

FILE *

fp

)

Set rpmlog file handle.

Parameters

fp	rpmlog file handle (NULL uses stdout/stderr)

Returns

previous rpmlog file handle

rpmlogSetMask()

int rpmlogSetMask

(

int

mask

)

Set the log mask level.

Parameters

mask	log mask (0 is no operation)

Returns

previous log mask
