Typedef Documentation

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.

typedef enum rpmlogFac_e rpmlogFac

facility codes

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)

typedef struct rpmlogRec_s* rpmlogRec

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.

Enumerator:

RPMLOG_EMERG	system is unusable

Function Documentation

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

Generate a log message using FMT string and option arguments.

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

void rpmlogClose

(

void

)

Close desriptor used to write to system logger.

Todo:

Implement.

Referenced by main().

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

int rpmlogGetNrecs

(

void

)

Return number of rpmError() ressages.

Returns:

number of messages

const char* rpmlogLevelPrefix

(

rpmlogLvl

pri

)

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

Parameters:

pri

log priority

Returns:

message prefix (or "" for none)

void const char* rpmlogMessage

void

)

Return text of last rpmError() message.
