## 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

Definition at line 163 of file rpmlog.h.

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
  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

## Function Documentation

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

Generate a log message using FMT string and option arguments.

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

void rpmlogClose | ( | void |  | ) |

Close desriptor used to write to system logger.

Todo:
  Implement.

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.

Returns:
  text of last message

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

Open connection to system logger.

Todo:
  Implement.

void rpmlogPrint | ( | FILE * | f | ) |

Print all rpmError() messages.

Parameters:

  f | file handle (NULL uses stderr)

const char* rpmlogRecMessage | ( | rpmlogRec | rec | ) |

Retrieve log message string from rpmlog record.

Parameters:

  rec | rpmlog record

Returns:
  log message

rpmlogLvl rpmlogRecPriority | ( | rpmlogRec | rec | ) |

Retrieve log priority from rpmlog record.

Parameters:

  rec | rpmlog record

Returns:
  log priority

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

FILE* rpmlogSetFile | ( | FILE * | fp | ) |

Set rpmlog file handle.

Parameters:

  fp | rpmlog file handle (NULL uses stdout/stderr)

Returns:
  previous rpmlog file handle

int rpmlogSetMask | ( | int | mask | ) |

Set the log mask level.

Parameters:

  mask | log mask (0 is no operation)

Returns:
  previous log mask
