5443 | * This interface is used at least by Solaris, HP-UX, IRIX, and Linux. | |
5444 | * (and SCO?) | |
5445 | * | |
5446 | * AIX getpwnam() is clever enough to return the encrypted password | |
5447 | * only if the caller (euid?) is root. | |
5448 | * | |
e549f1c5 | 5449 | * There are at least three other shadow password APIs. Many platforms |
bcf53261 JH |
5450 | * seem to contain more than one interface for accessing the shadow |
5451 | * password databases, possibly for compatibility reasons. | |
3813c136 | 5452 | * The getsp*() is by far he simplest one, the other two interfaces |

5480 | * <hpsecurity.h> instead of <sys/security.h>, but that is not needed | |
5481 | * if one includes <shadow.h> as that includes <hpsecurity.h>, | |
5482 | * and pp_sys.c already includes <shadow.h> if there is such. | |
3813c136 JH |
5483 | * |
5484 | * Note that <sys/security.h> is already probed for, but currently | |
5485 | * it is only included in special cases. | |
301e8125 | 5486 | * |
bcf53261 JH |
5487 | * In Digital UNIX/Tru64 if using the getespw*() (which seems to be |
5488 | * be preferred interface, even though also the getprpw*() interface | |
5489 | * is available) one needs to link with -lsecurity -ldb -laud -lm. | |
3813c136 JH |
5490 | * One also needs to call set_auth_parameters() in main() before |
5491 | * doing anything else, whether one is using getespw*() or getprpw*(). | |
5492 | * | |
