ACCT(2) Linux Programmer's Manual ACCT(2)
acct - switch process accounting on or off
#include <unistd.h>
int acct(const char *filename);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
acct(): _BSD_SOURCE || (_XOPEN_SOURCE && _XOPEN_SOURCE < 500)
The acct() system call enables or disables process accounting. If
called with the name of an existing file as its argument, accounting
is turned on, and records for each terminating process are appended
to filename as it terminates. An argument of NULL causes accounting
to be turned off.
On success, zero is returned. On error, -1 is returned, and errno is
set appropriately.
EACCES Write permission is denied for the specified file, or search
permission is denied for one of the directories in the path
prefix of filename (see also path_resolution(7)), or filename
is not a regular file.
EFAULT filename points outside your accessible address space.
EIO Error writing to the file filename.
EISDIR filename is a directory.
ELOOP Too many symbolic links were encountered in resolving
filename.
ENAMETOOLONG
filename was too long.
ENFILE The system limit on the total number of open files has been
reached.
ENOENT The specified filename does not exist.
ENOMEM Out of memory.
ENOSYS BSD process accounting has not been enabled when the operating
system kernel was compiled. The kernel configuration
parameter controlling this feature is CONFIG_BSD_PROCESS_ACCT.
ENOTDIR
A component used as a directory in filename is not in fact a
directory.
EPERM The calling process has insufficient privilege to enable
process accounting. On Linux the CAP_SYS_PACCT capability is
required.
EROFS filename refers to a file on a read-only file system.
EUSERS There are no more free file structures or we ran out of
memory.
SVr4, 4.3BSD (but not POSIX).
No accounting is produced for programs running when a system crash
occurs. In particular, nonterminating processes are never accounted
for.
The structure of the records written to the accounting file is
described in acct(5).
