== NAME
|
|
|
|
ll2_read_all - Reads all entries from database and calls the callback function for each entry.
|
|
|
|
== SYNOPSIS
|
|
|
|
*#include <lastlog2.h>*
|
|
*int ll2_read_all (struct ll2_context *__context__,
|
|
int (*__callback__)(const char *__user__, int64_t __ll_time__,
|
|
const char *__tty__, const char *__rhost__,
|
|
const char *__pam_service__, const char *__cb_error__),
|
|
char **__error__);*
|
|
|
|
== DESCRIPTION
|
|
|
|
Reads all entries from database, defined in _context_, and calls callback function _callback_ for each entry.
|
|
If _context_ is NULL, the default database, defined in _LL2_DEFAULT_DATABASE_, will be taken.
|
|
|
|
--------------------------------------
|
|
char *error = NULL;
|
|
const char *user = "root";
|
|
|
|
static int
|
|
callback (const char *res_user, int64_t ll_time, const char *res_tty,
|
|
const char *res_rhost, const char *res_service, const char *cb_error)
|
|
{
|
|
/* returning != 0 if no further entry has to be handled by the callback */
|
|
return 0;
|
|
}
|
|
|
|
int ret = ll2_read_all (NULL, callback, &error);
|
|
--------------------------------------
|
|
|
|
== RETURN VALUE
|
|
|
|
Returns 0 on success, -ENOMEM or -1 on other failure.
|
|
_error_ contains an error string if the return value is -1.
|
|
_error_ is not guaranteed to contain an error string, could also be NULL.
|
|
_error_ should be freed by the caller.
|
|
If lastlog2 database does not exist at all, the errno ENOENT is set
|
|
and can be checked.
