- create, destroy and manipulate exacct objects
cc [ flag… ] file… -lexacct [ library… ] #include <exacct.h> int ea_set_item(ea_object_t *obj, ea_catalog_t tag, void *value, size_t valsize);
void *ea_alloc(size_t size);
char *ea_strdup(char *ptr);
int ea_set_group(ea_object_t *obj, ea_catalog_t tag);
int ea_match_object_catalog(ea_object_t *obj, ea_catalog_t catmask);
void ea_attach_to_object(ea_object_t *head_obj, ea_object_t *obj);
void ea_attach_to_group(ea_object_t *group_obj, ea_object_t *obj);
void ea_free(void *ptr, size_t size);

int ea_free_item(ea_object_t *obj, int flag);
void ea_free_object(ea_object_t *obj, int flag);
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 specified 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 correspond to those specified in calls to ea_unpack_object(3EXACCT).
The ea_match_object_catalog() function returns 0 if the object's catalog 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 appropriately. Pointer-valued functions return a valid pointer if successful and NULL otherwise, setting the extended accounting error code appropriately. The extended accounting error code can be examined with ea_error(3EXACCT).
The ea_set_item(), ea_set_group(), and ea_match_object_catalog() functions may fail if:
A system call invoked by the function failed. The errno variable contains the error value set by the underlying call.
The passed object is of an incorrect type, for example passing a group object to ea_set_item().
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.
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)); ...
