/*!

The function ex_get_init() reads the initializationinitialization
parameters from an opened exodus file.

\return In case of an error, ex_get_init() 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().

\param exoid              exodus file ID returned from a previous call to ex_create() or ex_open().
\param[out] title         Returned database title. String length may be up to \c MAX_LINE_LENGTH bytes.
\param[out] num_dim       Returned dimensionality of the database. This is the number of coordinates per node.
\param[out] num_nodes     Returned number of nodal points.
\param[out] num_elem      Returned number of elements
\param[out] num_elem_blk  Returned number of element blocks
\param[out] num_node_sets Returned number of node sets
\param[out] num_side_sets Returned number of side sets

\sa ex_get_init_ext()

The following code segment will read the initialization parameters
from the open exodus file:

\code
#include "exodusII.h"
int num_dim, num_nodes, num_elem, num_elem_blk,
    num_node_sets, num_side_sets, error, exoid;

char title[MAX_LINE_LENGTH+1];
