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 189 of file rpmlog.h.

§ rpmlogCallbackData

typedef void* rpmlogCallbackData

§ 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.

Function Documentation

§ rpmlog()

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

Generate a log message using FMT string and option arguments.

Referenced by buildArgCallback(), buildForTarget(), checkSpec(), getTarSpec(), and isSpecFile().

§ 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
