Accessing Data with put_vara() and get_vara()

int (*put_vara)(int ncid, int varid, const size_t *start, const size_t *count,
                     const void *value, nc_type memtype);

int (*get_vara)(int ncid, int varid, const size_t *start, const size_t *count,
                void *value, nc_type memtype);

Most of the parameters are similar to the netcdf API parameters. The last parameter, however, is the type of the data in memory. Additionally, instead of using an "int islong" parameter, the memtype will be either NC_INT or NC_INT64, depending on the value of sizeof(long). This means that even netcdf-3 code must be prepared to encounter the NC_INT64 type.
