NAME

SYNOPSIS

9       #include <unistd.h>
10
11       int acct(const char *filename);
12
13   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
14
15       acct(): _BSD_SOURCE || (_XOPEN_SOURCE && _XOPEN_SOURCE < 500)
16

DESCRIPTION

18       The  acct()  system  call  enables  or disables process accounting.  If
19       called with the name of an existing file as its argument, accounting is
20       turned  on,  and  records  for each terminating process are appended to
21       filename as it terminates.  An argument of NULL causes accounting to be
22       turned off.
23

RETURN VALUE

25       On  success,  zero is returned.  On error, -1 is returned, and errno is
26       set appropriately.
27

ERRORS

29       EACCES Write permission is denied for the  specified  file,  or  search
30              permission is denied for one of the directories in the path pre‐
31              fix of filename (see also path_resolution(7)),  or  filename  is
32              not a regular file.
33
34       EFAULT filename points outside your accessible address space.
35
36       EIO    Error writing to the file filename.
37
38       EISDIR filename is a directory.
39
40       ELOOP  Too many symbolic links were encountered in resolving filename.
41
42       ENAMETOOLONG
43              filename was too long.
44
45       ENFILE The  system  limit  on  the  total number of open files has been
46              reached.
47
48       ENOENT The specified filename does not exist.
49
50       ENOMEM Out of memory.
51
52       ENOSYS BSD process accounting has not been enabled when  the  operating
53              system  kernel was compiled.  The kernel configuration parameter
54              controlling this feature is CONFIG_BSD_PROCESS_ACCT.
55
56       ENOTDIR
57              A component used as a directory in filename is  not  in  fact  a
58              directory.
59
60       EPERM  The calling process has insufficient privilege to enable process
61              accounting.  On Linux the CAP_SYS_PACCT capability is required.
62
63       EROFS  filename refers to a file on a read-only file system.
64
65       EUSERS There are no more free file structures or we ran out of memory.
66

CONFORMING TO

68       SVr4, 4.3BSD (but not POSIX).
69

NOTES

71       No accounting is produced for programs  running  when  a  system  crash
72       occurs.   In  particular,  nonterminating processes are never accounted
73       for.
74
75       The structure  of  the  records  written  to  the  accounting  file  is
76       described in acct(5).
