auditsvc - write audit records to specified file descriptor

---

SYNOPSIS

int auditsvc(fd, limit)
int fd;
int limit;

DESCRIPTION

The auditsvc() system call specifies the audit log file to the kernel. The kernel writes audit records to this file until an exceptional condition occurs and then the call returns. The parameter fd is a file descriptor that identifies the audit file. Programs should open this file for writing before calling auditsvc(). The parameter limit specifies a value between 0 and 100, instructing auditsvc() to return when the percentage of free disk space on the audit filesystem drops below this limit. Thus, the invoking program can take action to avoid running out of disk space. The auditsvc() system call does not return until one of the following conditions occurs:

• The process receives a signal that is not blocked or ignored.
• An error is encountered writing to the audit log file.
• The minimum free space (as specified by limit), has been reached.

Only processes with a real or effective user ID of super-user may execute this call successfully.

RETURN VALUES

auditsvc() returns only on an error.

ERRORS

EAGAIN

The descriptor referred to a stream, was marked for System V-style non-blocking I/O, and no data could be written immediately.

EBADF

fd is not a valid descriptor open for writing.

EBUSY

A second process attempted to perform this call.

A second process attempted to perform this call.

EDQUOT

The user's quota of disk blocks on the file system containing the file has been exhausted.

Audit filesystem space is below the specified limit.

EFBIG

An attempt was made to write a file that exceeds the process's file size limit or the maximum file size.

EINTR

The call is forced to terminate prematurely due to the arrival of a signal whose SV_INTERRUPT bit in sv_flags is set (see sigvec.2 signal.3v in the System V compatibility library, sets this bit for any signal it catches.

EINVAL

Auditing is disabled (see auditon.2

fd does not refer to a file of an appropriate type. Regular files are always appropriate.

EIO

An I/O error occurred while reading from or writing to the file system.

ENOSPC

There is no free space remaining on the file system containing the file.

ENXIO

A hangup occurred on the stream being written to.

EPERM

The process's effective or real user ID is not super-user.

EWOULDBLOCK

The file was marked for 4.2BSD-style non-blocking I/O, and no data could be written immediately.
