bcf53261 JH |

4925 | * password databases, possibly for compatibility reasons. | |
3813c136 | 4926 | * The getsp*() is by far he simplest one, the other two interfaces |

bcf53261 JH |
4961 | * In Digital UNIX/Tru64 if using the getespw*() (which seems to be |
4962 | * be preferred interface, even though also the getprpw*() interface | |
4963 | * is available) one needs to link with -lsecurity -ldb -laud -lm. | |
3813c136 JH |
4964 | * One also needs to call set_auth_parameters() in main() before |
4965 | * doing anything else, whether one is using getespw*() or getprpw*(). | |
