Section: 16 User Defined Types in NetCDF-4

16.0	Using User Defined Types User-defined types can be used to store N-dimensional arrays structs, variable length arrays, enumerations, and opaque data ojects of known size.
16.1	Writing and Reading Data of User Defined Type Use these functions to read or write data of user defined type.
16.2	Learning about User Defined Types Inquiry functions in netCDF-4 allow users to learn about user-defined types when reading a file.
16.3	Introduction to Compound Types Use compound types to group data together.
16.4	Compound Type CDL Example This CDL exampls shows a compound type.
16.5	Using Compound Types Compound types can store arrays of structures.
16.6	Using Enums The enumerated type can associate labels with names.
16.7	Uses of Enumerations What are the uses for enum data?
16.8	Enum CDL Example A CDL example shows enumerations which classify cloud types.
16.9	Enum Example This example shows how to use enums from the C API.
16.10	Using the Opaque Type The opaque type holds arrays of unknown contents, with known size.
16.11	Variable-Length Types Variable-Length types provide support for ragged arrays.
16.12	Introuction to Variable Length Types Variable length array types allow for the storage of ragged arrays.
16.13	CDL Example of Variable-Length Types This CDL example shows a 1D VLEN array.
16.14	Variable Length C Example This example shows the use of a VLEN type as an attribute.
16.15	Using Variable Length Types, Continued Memory for variable length array data is allocated by the library when they are read, and must be freed by the user.
16.16	Sea Sounding Example Code
16.17	Sea Sounding Example The ncdump output shows the type defined by nc_test4/cdm_sea_soundings.c.
