Kernel internal structures may change from release to release without warning. Applications directly rely-

ing on these structures are not supported.

Accounting ﬁles are currently written in 32-bit format. Thus, 64-bit applications which read the ﬁles need

to make special provisions. In particular, the

acct.h header declares the ac_btime ﬁeld as

int32_t rather than a time_t in 64-bit compilations. The

ac_btime ﬁeld should be cast to

time_t in the application before using it (for example, in calls to date conversion functions). The account-

ing ﬁle format will be changed to a 64-bit layout at a future release.
