The function ex_put_prop_array() stores an array of ({num_elem_blk},
\c num_node_sets, or \c num_side_sets) integer property values for all
element blocks, node sets, or side sets. The order of the values in
the array must correspond to the order in which the element blocks,
node sets, or side sets were introduced into the file. For instance,
if the parameters for element block with ID 20 were written to a file
(via ex_put_elem_block()), and then parameters for element block with
ID 10, followed by the parameters for element block with ID 30, the
first, second, and third elements in the property array would
correspond to element block 20, element block 10, and element block
30, respectively.

One should note that this same functionality (writing properties to
multiple objects) can be accomplished with multiple calls to
ex_put_prop().

Although it is not necessary to invoke ex_put_prop_names(), since
ex_put_prop_array() will allocate space within the data file if it
hasn't been previously allocated, it is more efficient to use
ex_put_prop_names() if there is more than one property to store. \see
See Efficiency for a discussion of efficiency issues.

\return In case of an error, ex_put_prop_array() returns a negative
number; a warning will return a positive number. Possible causes of
errors include:
  -  data file not properly opened with call to ex_create() or ex_open()
  -  data file opened for read only.
  -  data file not initialized properly with call to ex_put_init().
  -  invalid object type specified.

\param[in] exoid      exodus file ID returned from a previous call to ex_create() or ex_open().
\param[in] obj_type   Type of object; use one of the options in the table below.
\param[in] prop_name  The name of the property for which the values will be stored. Maximum
                      length of this string is \p MAX_STR_LENGTH .
\param[in] values     An array of property values.
