acct(2) 							   System Calls 							   acct(2)

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 SYNOPSIS
DESCRIPTION
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
