HP-UX Reference (11i v2 07/12) - 3 Library Functions A-M (vol 6)

bwtmps(3C) bwtmps(3C)

WARNINGS

Applications should not access the wtmps and btmps

databases directly, but should use these functions as

the structure written to these databases is a superset of the

utmps structure. updatebwdb() does not

update

/var/adm/wtmp

and /var/adm/btmp

ﬁles.

bwtmps(3C) interfaces load shared library

libuseracct.so.1/libuseracct.1

Compile/link for Archive Applications (PA-RISC only)

If you use bwtmps(3C) interfaces and compile/link your application archive, please note that bwtmps(3C)

interfaces have a dependency on

libdld.sl that will require a change to the compile/link command:

Compile :

cc -Wl,-a,archive -Wl,-E -Wl,+n -l:libdld.sl -o

outﬁle source

Or compile with

CCOPTS and LDOPTS:

export CCOPTS="-Wl,-a,archive options -Wl,-E -l:libdld.sl"

export LDOPTS="options -E +n -l:libdld.sl"

cc -o

outﬁle source

The option -Wl,-a,archive is positionally dependent and should occur at the beginning of the compile

line. For optimum compatibility in future releases, you should avoid using archive libc with other shared

libraries except for

libdld.sl as needed above.

The bwtmps routines were developed by Hewlett-Packard Company.
