NAME
acct - enable or disable process accounting SYNOPSIS
#include <unistd.h> int acct(const char *path); DESCRIPTION
The acct() function enables or disables the system process accounting routine. If the routine is enabled, an accounting record will be written in an accounting file for each process that terminates. The termination of a process can be caused by either an exit(2) call or a signal(3C)). The effective user ID of the process calling acct() must have the appropriate privileges. The path argument points to the pathname of the accounting file, whose file format is described on the acct.h(3HEAD) manual page. The accounting routine is enabled if path is non-zero and no errors occur during the function. It is disabled if path is (char *)NULL and no errors occur during the function. RETURN VALUES
Upon successful completion, 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error. ERRORS
The acct() function will fail if: EACCES The file named by path is not an ordinary file. EBUSY An attempt is being made to enable accounting using the same file that is currently being used. EFAULT The path argument points to an illegal address. ELOOP Too many symbolic links were encountered in translating path. ENAMETOOLONG The length of the path argument exceeds {PATH_MAX}, or the length of a path argument exceeds {NAME_MAX} while _POSIX_NO_TRUNC is in effect. ENOENT One or more components of the accounting file pathname do not exist. ENOTDIR A component of the path prefix is not a directory. EPERM The {PRIV_SYS_ACCT} privilege is not asserted in the effective set of the calling process. EROFS The named file resides on a read-only file system. SEE ALSO

NAME
acct -- enable or disable process accounting LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <unistd.h> int acct(const char *file); DESCRIPTION
The acct() call enables or disables the collection of system accounting records. If file is NULL, accounting is disabled. If file is an existing, NUL-terminated, pathname, record collection is enabled, and for every process initiated which terminates under normal conditions an accounting record is appended to file. Abnormal conditions of termination are reboots or other fatal system problems. Records for processes which never terminate can not be produced by acct(). For more information on the record structure used by acct(), see /usr/include/sys/acct.h and acct(5). This call is permitted only to the super-user. NOTES
Accounting is automatically disabled when the file system the accounting file resides on runs out of space; it is enabled when space once again becomes available. For this purpose, acct() creates a kernel thread called ``acctwatch''. RETURN VALUES
On success, zero is returned. Otherwise, -1 is returned and errno is set to indicate the error. ERRORS
acct() will fail if one of the following is true: [EACCES] Search permission is denied for a component of the path prefix, or the path name is not a regular file. [EFAULT] file points outside the process's allocated address space. [EIO] An I/O error occurred while reading from or writing to the file system. [ELOOP] Too many symbolic links were encountered in translating the pathname. [ENAMETOOLONG] A component of a pathname exceeded {NAME_MAX} characters, or an entire path name exceeded {PATH_MAX} characters. [ENOENT] The named file does not exist. [ENOTDIR] A component of the path prefix is not a directory. [EPERM] The caller is not the super-user. [EROFS] The named file resides on a read-only file system. Also, acct() fails if failed to create kernel thread described above. See fork(2) for errno value. SEE ALSO
