## Function Documentation

rpmpsm rpmpsmFree | ( | rpmpsm | psm ) |

Destroy a package state machine.

Parameters:

  psm | package state machine

Returns:
  NULL always

Definition at line 1326 of file psm.c.

Referenced by _processFailedPackage(), rpmtsRun(), and rpmVerifyScript().

rpmpsm rpmpsmLink | ( | rpmpsm | psm,
|  | const char * | msg
| ) |  |

Reference a package state machine instance.

Parameters:

  psm | package state machine
  msg |

Returns:
  new package state machine reference

Referenced by rpmpsmNew().

rpmpsm rpmpsmNew | ( | rpmts | ts,
|  | rpmte | te,
|  | rpmfi | fi
| ) |  |

Create and load a package state machine.

Parameters:

  ts | transaction set
  te | transaction set element
  fi | file info set

Returns:
  new package state machine

Definition at line 1359 of file psm.c.

Referenced by _processFailedPackage(), rpmtsRun(), and rpmVerifyScript().

rpmRC rpmpsmStage | ( | rpmpsm | psm,
|  | pkgStage | stage
| ) |  |

Package state machine driver.

Parameters:

  psm | package state machine data
  stage | next stage

Returns:
  0 on success

Todo:
  Packages w/o files never get a callback, hence don't get displayed on install with -v.
