acct

       #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-wide 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.

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