* libmisc/age.c: Added brackets and parenthesis.
* libmisc/age.c: Ignore the return value of fclose (file opened
read-only)
* libmisc/age.c: Ignore puts() return value.
* libmisc/age.c: Use exit(EXIT_FAILURE) instead of exit(1).
* libmisc/age.c: Avoid assignments in comparisons.
* src/lastlog.c: Added splint annotations.
* src/lastlog.c: Avoid global pwent.
* src/lastlog.c: Cast ID to ulongs and use ulong formats for IDs.
* src/lastlog.c: Avoid assignment in comparisons.
* src/lastlog.c: Ignore fclose() return value since the file is
only opened for reading.
used_gids.
* libmisc/find_new_gid.c: Use getdef_ulong and cast to git_t to
get GID values.
* libmisc/find_new_gid.c: Use UL as a prefix for ulong values.
* libmisc/find_new_uid.c: Likewise.
default to 32.
* libmisc/chkname.c: Use USER_NAME_MAX_LENGTH.
* src/login.c: Use USER_NAME_MAX_LENGTH instead of the default 32.
username also needs to be bigger than USER_NAME_MAX_LENGTH because
it has to be nul-terminated.
change the terminal configuration. setup_tty() is just a best
effort configuration of the terminal.
* src/login.c: Ignore failures when setting the terminal
configuration.
* src/login.c: Fail if the ERASECHAR or KILLCHAR configurations
are not compatible with a cc_t type.
of global utent/utxent variables. Only reuse the ut_id and maybe
the ut_host fields from utmp.
* lib/prototypes.h, libmisc/utmp.c: Removed checkutmp(),
setutmp(), setutmpx().
* lib/prototypes.h, libmisc/utmp.c: Added get_current_utmp(),
prepare_utmp(), prepare_utmpx(), setutmp(), setutmpx().
* libmisc/utmp.c (is_my_tty): Only compare the name of the utmp
line with ttyname(). (No stat of the two terminals to compare the
devices).
* libmisc/utmp.c: Use getaddrinfo() to get the address of the
host.
* configure.in: Check for getaddrinfo().
* configure.in: Use AC_CHECK_MEMBERS to check for the existence of
fields in the utmp/utmpx structures.
* configure.in: Reject systems with utmpx support but no ut_id
field in utmp. This could be fixed later if needed.
* src/login.c: Use the new utmp functions. This also simplifies
the failtmp() handling.
* src/login.c: passwd_free() renamed to pw_free() and
shadow_free() renamed to spw_free()
* lib/shadowio.c: Use spw_free() for shadow_free().
* lib/groupmem.c: Added gr_free().
* lib/groupio.c: Use gr_free() for group_free().
* lib/pwmem.c: Include define.h before prototypes.h
* lib/pwmem.c: Added pw_free().
* lib/pwio.c: Use pw_free() for passwd_free().
* lib/sgroupio.c: Added sgr_free().
* lib/sgroupio.c: Use sgr_free() for gshadow_free().
* lib/prototypes.h: Added gr_free(), pw_free(), sgr_free(),
spw_free().
