Read an array of values from a variable.
The array to be read is specified by giving a corner and a vector of
edge lengths to \ref specify_hyperslab.
The data values are read into consecutive locations with the last
dimension varying fastest. The netCDF dataset must be in data mode
(for netCDF-4/HDF5 files, the switch to data mode will happen
automatically, unless the classic model is used).
The nc_get_vara() function will read a variable of any type,
including user defined type. For this function, the type of the data
in memory must match the type of the variable - no data conversion is
done.
Other nc_get_vara_ functions will convert data to the desired output
type as needed.
\param ncid NetCDF or group ID, from a previous call to nc_open(),
nc_create(), nc_def_grp(), or associated inquiry functions such as
nc_inq_ncid().
\param varid Variable ID
\param startp Start vector with one element for each dimension to \ref
specify_hyperslab.
\param countp Count vector with one element for each dimension to \ref
specify_hyperslab.
\param ip Pointer where the data will be copied. Memory must be
allocated by the user before this function is called.

the variable named rh from an existing netCDF dataset named
foo.nc. For simplicity in this example, we assume that we know that rh
is dimensioned with time, lat, and lon, and that there are three time
values, five lat values, and ten lon values.
\code
#include <netcdf.h>
...
#define TIMES 3
#define LATS 5
#define LONS 10
int status;
int ncid;
int rh_id;
static size_t start[] = {0, 0, 0};
static size_t count[] = {TIMES, LATS, LONS};
double rh_vals[TIMES*LATS*LONS];
...
status = nc_open("foo.nc", NC_NOWRITE, &ncid);
if (status != NC_NOERR) handle_error(status);
...
status = nc_inq_varid (ncid, "rh", &rh_id);

/** \ingroup variables
Read an entire variable in one call.
This function will read all the values from a netCDF variable of an
open netCDF dataset.
This is the simplest interface to use for reading the value of a
scalar variable or when all the values of a multidimensional variable
can be read at once. The values are read into consecutive locations
with the last dimension varying fastest. The netCDF dataset must be in
data mode.
Take care when using this function with record variables (variables
that use the ::NC_UNLIMITED dimension). If you try to read all the
values of a record variable into an array but there are more records
in the file than you assume, more data will be read than you expect,
which may cause a segmentation violation. To avoid such problems, it
is better to use the nc_get_vara interfaces for variables that use the
::NC_UNLIMITED dimension.
The functions for types ubyte, ushort, uint, longlong, ulonglong, and
string are only available for netCDF-4/HDF5 files.
The nc_get_var() function will read a variable of any type, including
