DESCRIPTION

233       The papiAttributeListAdd*() functions add new attributes and/or  values
234       to  the  attribute  list  passed  in.  If necessary, the attribute list
235       passed in is expanded to contain a new attribute pointer  for  any  new
236       attributes  added  to  the list. The list is null-terminated. Space for
237       the new attributes and values is allocated and the name and  value  are
238       copied into this allocated space.
239
240
241       If PAPI_ATTR_REPLACE is specified in flags, any existing attribute val‐
242       ues are freed and replaced with the supplied value.
243
244
245       If PAPI_ATTR_APPEND is specified, the supplied value is appended to the
246       attribute's list of values.
247
248
249       If  PAPI_ATTR_EXCL  is  specified,  the  operation succeeds only if the
250       attribute was not previously defined.
251
252
253       The papiAttributeListGet*() functions retrieve an attribute value  from
254       an  attribute  list.  If the attribute is a multi-valued attribute, the
255       first call to retrieve a value should pass in an iterator and attribute
256       name. Subsequent calls to retrieve additional values should pass in the
257       iterator and a null value for the attribute name.  If  a  single-valued
258       attribute  is  to be retrieved, NULL can be used in place of the itera‐
259       tor.
260
261
262       Upon successful completion of a get  operation,  the  value  passed  in
263       (string,  integer,  boolean,  ...)  is  changed  to  the value from the
264       attribute list.  If the operation fails for any reason (type  mismatch,
265       not found, ...), the value passed in remains untouched.
266
267
268       The  resulting value returned from a get operation is returned from the
269       attribute list's allocated memory. It is not guaranteed to be available
270       after the attribute list has been freed.
271
272
273       The papiAttributeListDelete() function removes an attribute from a sup‐
274       plied list.
275
276
277       The papiAttributeListFind() function allows an application to  retrieve
278       an entire attribute structure from the passed-in attribute list.
279
280
281       The  papiAttributeListGetNext()  function allows an application to walk
282       through an attribute list  returning  subsequent  attributes  from  the
283       list.   With the first call, the iterator should be initialized to NULL
284       and subsequent calls should use NULL for the list argument.
285
286
287       The papiAttributeListFree() function deallocates all memory  associated
288       with an attribute list, including values that might have been retrieved
289       previously using papiAttributeListGet*() calls.
290
291
292       The papiAttributeListFromString() function takes in a string  represen‐
293       tation  of  a  set  of  attributes,  parses  the  string  and  adds the
294       attributes to the passed in attribute list using the flags to determine
295       how to add them.  String values are specified with "key=value". Integer
296       values are specified with "key=number". Boolean  values  are  specified
297       with either "key=(true|false)" or "[no]key". Multiple attributes can be
298       specified in the string by separating them with a whitespace character.
299
300
301       The papiAttributeListToString() function converts an attribute list  to
302       a string representation that can be displayed to a user.  The delimiter
303       value is placed between attributes in the string.
304

RETURN VALUES

306       These functions return PAPI_OK upon successful completion  and  one  of
307       the following on failure:
308
309       PAPI_BAD_ARGUMENT       The supplied arguments were not valid.
310
311
312       PAPI_CONFLICT           There was an attribute type mismatch.
313
314
315       PAPI_NOT_FOUND          The requested attribute could not be found.
316
317
318       PAPI_NOT_POSSIBLE       The  requested operation could not be performed
319                               due to buffer overflow.
320
321
322       PAPI_TEMPORARY_ERROR    Memory could not be allocated  to  add  to  the
323                               attribute list.
