/**
* @ingroup PIO_def_var
* Set chunksizes for a variable.
*
* This function only applies to netCDF-4 files. When used with netCDF
* classic files, the error PIO_ENOTNC4 will be returned.
*
* See the <a
* href="http://www.unidata.ucar.edu/software/netcdf/docs/group__variables.html">netCDF
* variable documentation</a> for details about the operation of this
* function.
*
* Chunksizes have important performance repercussions. NetCDF
* attempts to choose sensible chunk sizes by default, but for best
* performance check chunking against access patterns.
*
* @param ncid the ncid of the open file.
* @param varid the ID of the variable to set chunksizes for.
* @param storage NC_CONTIGUOUS or NC_CHUNKED.
* @param chunksizep an array of chunksizes. Must have a chunksize for
* every variable dimension.
*
* @return PIO_NOERR for success, otherwise an error code.
