Detailed Description

RPM Logging facilities.

Typedef Documentation

◆ rpmlogCallback

typedef int(* rpmlogCallback) (rpmlogRec rec, rpmlogCallbackData data)
Parameters
recrpmlog record
dataprivate 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.

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
prilog 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
ffile handle (NULL uses stderr)

◆ rpmlogRecMessage()

const char* rpmlogRecMessage ( rpmlogRec  rec)

Retrieve log message string from rpmlog record

Parameters
recrpmlog record
Returns
log message

◆ rpmlogRecPriority()

rpmlogLvl rpmlogRecPriority ( rpmlogRec  rec)

Retrieve log priority from rpmlog record

Parameters
recrpmlog record
Returns
log priority

◆ rpmlogSetCallback()

rpmlogCallback rpmlogSetCallback ( rpmlogCallback  cb,
rpmlogCallbackData  data 
)

Set rpmlog callback function.

Parameters
cbrpmlog callback function
datacallback private (user) data
Returns
previous rpmlog callback function

◆ rpmlogSetFile()

FILE* rpmlogSetFile ( FILE *  fp)

Set rpmlog file handle.

Parameters
fprpmlog file handle (NULL uses stdout/stderr)
Returns
previous rpmlog file handle

◆ rpmlogSetMask()

int rpmlogSetMask ( int  mask)

Set the log mask level.

Parameters
masklog mask (0 is no operation)
Returns
previous log mask
