a
audctl(2) audctl(2)
(TO BE OBSOLETED)
NAME
audctl() - start or halt the auditing system and set or get audit files
SYNOPSIS
#include <sys/audit.h>
int audctl(int cmd, char *cpath, char *npath, mode_t mode);
Remarks
This function is provided purely for backward compatibility. HP recommends that new applications use the
audsys command to configure the auditing system. See audsys(1M).
DESCRIPTION
audctl() sets or gets the auditing system "current" and "next" audit files, and starts or halts the audit-
ing system. This call is restricted to processes with the
AUDCONTROL privilege. cpath and npath hold the
absolute path names of the "current" and "next" files. mode specifies the audit file’s permission bits. cmd is
one of the following specifications:
AUD_ON The caller issues the AUD_ON command with the required "current" and "next" files to
turn on the auditing system. If the auditing system is currently off, it is turned on;
the file specified by the cpath parameter is used as the "current" audit file, and the file
specified by the npath parameter is used as the "next" audit file. If the audit files do
not already exist, they are created with the mode specified. The auditing system then
begins writing to the specified "current" file. An empty string or NULL npath can be
specified if the caller wants to designate that no "next" file be available to the auditing
system. If the auditing system is already on, no action is performed;
-1 is returned
and
errno is set to [EBUSY].
AUD_GET The caller issues the AUD_GET command to retrieve the names of the "current" and
"next" audit files. If the auditing system is on, the names of the "current" and "next"
audit files are returned via the cpath and npath parameters (which must point to
character buffers of sufficient size to hold the file names). mode is ignored. If the
auditing system is on and there is no available "next" file, the "current" audit file name
is returned via the cpath parameter, npath is set to an empty string;
-1 is returned,
and
errno is set to [ENOENT]. If the auditing system is off, no action is performed;
-1 is returned and errno is set to [EALREADY].
AUD_SET The caller issues the AUD_SET command to change both the "current" and "next"
files. If the audit system is on, the file specified by cpath is used as the "current" audit
file, and the file specified by npath is used as the "next" audit file. If the audit files do
not already exist, they are created with the specified mode. The auditing system
begins writing to the specified "current" file. Either an empty string or NULL npath
can be specified if the caller wants to designate that no "next" file be available to the
auditing system. If the auditing system is off, no action is performed;
-1
is returned
and
errno is set to [EALREADY].
AUD_SETCURR
The caller issues the AUD_SETCURR command to change only the "current" audit file.
If the audit system is on, the file specified by cpath is used as the "current" audit file.
If the specified "current" audit file does not exist, it is created with the specified mode.
npath is ignored. The auditing system begins writing to the specified "current" file. If
the audit system is off, no action is performed;
-1 is returned and errno is set to
[EALREADY].
AUD_SETNEXT
The caller issues the AUD_SETNEXT command to change only the "next" audit file. If
the auditing system is on, the file specified by npath is used as the "next" audit file.
cpath is ignored. If the "next" audit file specified does not exist, it is created with the
specified mode. Either an empty string or NULL npath can be specified if the caller
wants to designate that no "next" file be available to the auditing system. If the audit-
ing system is off, no action is performed; -1 is returned, and errno is set to [EAL-
READY].
AUD_SWITCH The caller issues the AUD_SWITCH command to cause the auditing system to switch
audit files. If the auditing system is on, it uses the "next" file as the new "current"
audit file and sets the new "next" audit file to NULL. cpath, npath,and mode are
