       void ea_free(void *ptr, size_t size);

       void ea_strfree(char *ptr);

       int ea_free_item(ea_object_t *obj, int flag);

       void ea_free_object(ea_object_t *obj, int flag);

DESCRIPTION
       The  ea_alloc()	function  allocates a block of memory of the requested
       size. This block can be safely passed to libexacct functions,  and  can
       be safely freed by any of the ea_free() functions.

       The  ea_strdup()	 function can be used to duplicate a string that is to
       be stored inside an ea_object_t structure.

       The ea_set_item() function  assigns the given exacct  object  to	 be  a
       data  item  with	 value	set according to the remaining arguments.  For
       buffer-based data values (EXT_STRING, EXT_EXACCT_OBJECT, and  EXT_RAW),
       a copy of the passed buffer is taken. In the case of EXT_EXACCT_OBJECT,
       the passed buffer should be a  packed  exacct  object  as  returned  by
       ea_pack_object(3EXACCT). Any item assigned with ea_set_item() should be
       freed with ea_free_item() specifying a flag value of EUP_ALLOC when the
       item is no longer needed.

       The  ea_match_object_catalog()  function	 returns  TRUE	if  the exacct
       object specified by obj has a catalog tag that matches the mask	speci‐
       fied by catmask.

       The  ea_attach_to_object()  function  attaches  an  object to the given
       object. The ea_attach_to_group() function attaches a chain  of  objects
       as  member items of the given group. Objects are inserted at the end of
       the list of any previously attached objects.

       The ea_free() function frees a block of memory previously allocated  by
       ea_alloc().

       The   ea_strfree()   function  frees  a	string	previously  copied  by
       ea_strdup().

       The ea_free_item() function frees the value fields in  the  ea_object_t
       indicated  by  obj, if EUP_ALLOC is specified. The object itself is not
       freed. The ea_free_object() function frees the specified object and any
       attached	 hierarchy  of	objects.  If  the  flag	 argument  is  set  to
       EUP_ALLOC, ea_free_object() will also free any variable-length data  in
       the  object hierarchy; if set to EUP_NOALLOC, ea_free_object() will not
       free variable-length data.  In particular, these	 flags	should	corre‐
       spond to those specified in calls to ea_unpack_object(3EXACCT).

RETURN VALUES
       The  ea_match_object_catalog() function returns 0 if the object's cata‐
       log tag does not match the given mask, and 1 if there is a match.

       Other integer-valued functions return 0 if successful. Otherwise	 these
       functions  return  -1 and set the extended accounting error code appro‐
       priately. Pointer-valued functions return a valid pointer if successful
       and  NULL  otherwise, setting the extended accounting error code appro‐
       priately. The extended accounting  error	 code  can  be	examined  with
       ea_error(3EXACCT).

ERRORS
       The  ea_set_item(), ea_set_group(), and ea_match_object_catalog() func‐
       tions may fail if:

       EXR_SYSCALL_FAIL	       A system call invoked by the  function  failed.
			       The errno variable contains the error value set
			       by the underlying call.

       EXR_INVALID_OBJECT      The passed object is of an incorrect type,  for
			       example	  passing    a	  group	   object   to
			       ea_set_item().

USAGE
       The exacct file format can be used to represent data other than that in
       the  extended accounting format.	 By using a unique creator type in the
       file header, application writers can develop their own format suited to
       the needs of their application.

EXAMPLES
       Example 1: Open and close exacct file.

       Construct  an  exacct file consisting of a single object containing the
       current process ID.

       #include <sys/types.h>
       #include <unistd.h>
       #include <exacct.h>

       ...

       ea_file_t ef;
       ea_object_t obj;
       pid_t my_pid;

       my_pid = getpid();
       ea_set_item(&obj, EXT_UINT32 | EXC_DEFAULT | EXT_PROC_PID,
	      &my_pid, sizeof(my_pid));

       ...
