Reads a mapped array section of values from a netCDF variable.
The mapped array section is specified by giving a corner, a vector of edge lengths, a stride vector, and an
index mapping vector. The index mapping vector is a vector of integers that specifies the mapping between the
dimensions of a netCDF variable and the in-memory structure of the internal data array. No assumptions are
made about the ordering or length of the dimensions of the data array.
\param start
Vector specifying the index in the variable where the first of the data values will be read.
The indices are relative to 0, so for example, the first data value of a variable would have index (0, 0, ... , 0).
The length of start must be the same as the number of dimensions of the specified variable.
The elements of start correspond, in order, to the variable's dimensions. Hence, if the variable is a record variable,
the first index would correspond to the starting record number for reading the data values.
\param count

To read a single value, for example, specify count as (1, 1, ... , 1). The length of count is the number of
dimensions of the specified variable. The elements of count correspond, in order, to the variable's dimensions.
Hence, if the variable is a record variable, the first element of count corresponds to a count of the number of records to read.
Note: setting any element of the count array to zero causes the function to exit without error, and without doing anything.
\param stride
Vector specifying the interval between selected indices. The elements of the stride vector correspond, in order,
to the variable's dimensions. A value of 1 accesses adjacent values of the netCDF variable in the corresponding
dimension; a value of 2 accesses every other value of the netCDF variable in the corresponding dimension; and so
on. A NULL stride argument is treated as (1, 1, ... , 1).
\param imap
Vector of integers that specifies the mapping between the dimensions of a netCDF variable and the in-memory
structure of the internal data array. imap[0] gives the distance between elements of the internal array corresponding
to the most slowly varying dimension of the netCDF variable. imap[n-1] (where n is the rank of the netCDF variable)
gives the distance between elements of the internal array corresponding to the most rapidly varying dimension of the
netCDF variable. Intervening imap elements correspond to other dimensions of the netCDF variable in the obvious way.
Distances between elements are specified in type-independent units of elements (the distance between internal elements
that occupy adjacent memory locations is 1 and not the element's byte-length as in netCDF 2).
\param dataValues Pointer to the location into which the data value is read. If the type of
data value differs from the netCDF variable type, type conversion will occur.
(However, no type conversion is carried out for variables using the user-defined data types:

Writes the entire data into the netCDF variable.
This is the simplest interface to use for writing a value in a scalar variable
or whenever all the values of a multidimensional variable can all be
written at once. The values to be written are associated with the
netCDF variable by assuming that the last dimension of the netCDF
variable varies fastest in the C interface.
Take care when using the simplest forms of this interface with
record variables when you don't specify how many records are to be
written. If you try to write all the values of a record variable
into a netCDF file that has no record data yet (hence has 0 records),
nothing will be written. Similarly, if you try to write all of a record
variable but there are more records in the file than you assume, more data
may be written to the file than you supply, which may result in a
segmentation violation.
\param dataValues The data values. The order in which the data will be written to the netCDF variable is with the last
dimension of the specified variable varying fastest. If the type of data values differs from the netCDF variable type, type conversion will occur.
(However, no type conversion is carried out for variables using the user-defined data types:
nc_Vlen, nc_Opaque, nc_Compound and nc_Enum.)

Writes a mapped array section of values into the netCDF variable.
The mapped array section is specified by giving a corner, a vector of counts, a stride vector, and an index mapping vector.
The index mapping vector is a vector of integers that specifies the mapping between the dimensions of a netCDF variable and the in-memory structure of the internal data array.
No assumptions are made about the ordering or length of the dimensions of the data array.
\param countp Vector specifying the number of indices selected along each dimension.
To write a single value, for example, specify count as (1, 1, ... , 1). The elements of
count correspond, in order, to the variable's dimensions. Hence, if the variable is a record

The elements of the index mapping vector correspond, in order, to the netCDF variable's dimensions (imap[0] gives the distance between elements
of the internal array corresponding to the most slowly varying dimension of the netCDF variable). Distances between elements are
specified in type-independent units of elements (the distance between internal elements that occupy adjacent memory locations is
1 and not the element's byte-length as in netCDF 2). A NULL argument means the memory-resident values have the same structure as
the associated netCDF variable.
\param dataValues The data values. The order in which the data will be written to the netCDF variable is with the last
dimension of the specified variable varying fastest. If the type of data values differs from the netCDF variable type, type conversion will occur.
