Update.
2004-02-26 Ulrich Drepper <drepper@redhat.com> * nss/getXXbyYY_r.c: Pass result also to the nscd_* function. Don't set *result here. * nscd/nscd_proto.h: Add new argument for pointer to result pointer to all nscd_* functions. * nscd/nscd_getgr_r.c (nscd_getgr_r): Add new parameter. Store result pointer in the address provided by the new parameter if successful. Otherwise store NULL. Return zero if no entry found. (__nscd_getgrnam_r, __nscd_getgrgid_r): Add new parameter and pass it on. * nscd/nscd_gethst_r.c (nscd_gethst_r): Add new parameter. Store result pointer in the address provided by the new parameter if successful. Otherwise store NULL. Return zero if no entry found. (__nscd_gethostbyname_r, __nscd_gethostbyname2_r, __nscd_gethostbyaddr_r): Add new parameter and pass it on. * nscd/nscd_getpw_r.c (nscd_getpw_r): Add new parameter. Store result pointer in the address provided by the new parameter if successful. Otherwise store NULL. Return zero if no entry found. (__nscd_getpwnam_r, __nscd_getpwuid_r): Add new parameter and pass it on.
