acct(2) 							System Calls Manual							   acct(2)

NAME
acct - Enables and disables process accounting SYNOPSIS
int acct ( char *path ); PARAMETERS
Specifies a pointer to the pathname of the file, or specifies a null pointer. DESCRIPTION
The acct() function enables and disables UNIX process accounting. When enabled, process accounting produces an accounting record on behalf of each terminating process. The path parameter specifies the pathname of the file to which an accounting record is written. When the path parameter is 0 (zero) or a null value, the acct() function disables the accounting routine. If the path parameter refers to a symbolic link, the acct() function writes records to the file pointed to by the symbolic link. If Network File System is installed on your system, the accounting file can reside on another node. To ensure accurate accounting, each node must have its own accounting file, which can be located on any node in the network. The calling process must have superuser privilege to enable or disable process accounting. RETURN VALUES
Upon successful completion, the acct() function returns a value of 0 (zero). Otherwise, a value of -1 is returned and errno is set to indicate the error. ERRORS
If the acct() function fails, errno may be set to one of the following values: The calling process does not have appropriate system privi- lege. The file named by the path parameter does not exist. The file named by the path parameter is not an ordinary file. Write permission is denied for the named accounting file. The named file resides on a read-only file system. RELATED INFORMATION

NAME
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
