setutxent(void)
getutxent()
reads the next entry from the database;
if the database was not yet open, it also opens it.
setutxent()
resets the database, so that the next
getutxent()
call will get the first entry.
endutxent()
closes the database.
getutxid()
returns the next entry of the type specified in its argument's
ut_type
field, or
NULL
if none is found.
getutxline()
returns the next
LOGIN_PROCESS
or
USER_PROCESS
entry which has the same name as specified in the
ut_line
field, or
NULL
if no match is found.
pututxline()
adds the argument
utmpx(5)
entry line to the accounting database, replacing a previous entry for
the same user if it exists.
