ACCT(2)			   Linux Programmer's Manual		       ACCT(2)

NAME
       acct - switch process accounting on or off

SYNOPSIS
       #include <unistd.h>

       int acct(const char *filename);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       acct(): _BSD_SOURCE || (_XOPEN_SOURCE && _XOPEN_SOURCE < 500)

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

RETURN VALUE
       On  success,  zero is returned.	On error, -1 is returned, and errno is
       set appropriately.

ERRORS
       EACCES Write permission is denied for the  specified  file,  or	search
	      permission is denied for one of the directories in the path pre‐
	      fix of filename (see also path_resolution(7)),  or  filename  is
	      not a regular file.

       EFAULT filename points outside your accessible address space.

       EIO    Error writing to the file filename.

       EISDIR filename is a directory.

       ELOOP  Too many symbolic links were encountered in resolving filename.

       ENAMETOOLONG
	      filename was too long.

       ENFILE The  system  limit  on  the  total number of open files has been
	      reached.

       ENOENT The specified filename does not exist.

       ENOMEM Out of memory.

       ENOSYS BSD process accounting has not been enabled when	the  operating
	      system  kernel was compiled.  The kernel configuration parameter
	      controlling this feature is CONFIG_BSD_PROCESS_ACCT.

       ENOTDIR
	      A component used as a directory in filename is  not  in  fact  a
	      directory.

       EPERM  The calling process has insufficient privilege to enable process
	      accounting.  On Linux the CAP_SYS_PACCT capability is required.

       EROFS  filename refers to a file on a read-only filesystem.

       EUSERS There are no more free file structures or we ran out of memory.

CONFORMING TO
       SVr4, 4.3BSD (but not POSIX).

NOTES
       No accounting is produced for programs  running	when  a	 system	 crash
       occurs.	 In  particular,  nonterminating processes are never accounted
       for.

       The structure  of  the  records	written	 to  the  accounting  file  is
       described in acct(5).
