acct() - enable or disable process accounting SYNOPSIS
The system call enables or disables the system's process accounting routine. If the routine is enabled, an accounting record is written on an accounting file for each process that terminates. Termination can be caused by one of two things: an call or a signal (see exit(2) and signal(5)). The calling process must have the privilege to use this call. path points to a path name naming the accounting file. The accounting file format is described in acct(4). The accounting routine is enabled if path is nonzero and no errors occur during the system call. It is disabled if path is zero and no errors occur during the system call. When the amount of free space on the file system containing the accounting file falls below a configurable threshold, the system prints a message on the console and disables process accounting. Another message is printed and the process accounting is re-enabled when the space reaches a second configurable threshold. If the size of the process accounting file reaches a configurable limit, records for processes terminating after that point will be silently lost. However, in that case the command would still sense that process accounting is still enabled. This loss of records can be prevented with the command. and are described in acctsh(1M)). Security Restrictions Some or all of the actions associated with this system call require the privilege. Processes owned by the superuser have this privilege. Processes owned by other users may have this privilege, depending on system configuration. See privileges(5) for more information about privileged access on systems that support fine-grained privileges. RETURN VALUE
returns the following values: Successful completion. Failure. is set to indicate the error. ERRORS
If fails, is set to one of the following values. The file named by path is not an ordinary file. An attempt is being made to enable accounting when it is already enabled. path points to an illegal address. The reliable detection of this error is implementation dependent. Too many symbolic links were encountered in translating the path name. The accounting file path name exceeds bytes, or the length of a component of the path name exceeds bytes while is in effect. One or more components of the accounting file path name do not exist. A component of the path prefix is not a directory. The calling process does not possess the privilege. The named file resides on a read-only file system. path points to a text file which is currently open. SEE ALSO

acct -- enable or disable process accounting SYNOPSIS
#include <unistd.h> int acct(const char *file); DESCRIPTION
The acct() call enables or disables the collection of system accounting records. If the argument file is a nil pointer, accounting is dis- abled. If file is an existing pathname (null-terminated), 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 prob- lems. 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. RETURN VALUES
The acct() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indicate the error. The file must exist and the call may be exercised only by the super-user. ERRORS
acct() will fail if one of the following is true: [EPERM] The caller is not the super-user. [ENOTDIR] A component of the path prefix is not a directory. [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. [EACCES] Search permission is denied for a component of the path prefix, or the path name is not a regular file. [ELOOP] Too many symbolic links were encountered in translating the pathname. [EROFS] The named file resides on a read-only file system. [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. SEE ALSO
