The _netcdf_dim_info dataset (in group _netCDF) contains the ids of the shared dimensions, and their length (0 for unlimited dimensions).

The _netcdf_var_info dataset (in group _netCDF) holds an array of compound types which contain the variable ID, and the associated dimension ids.

Global nc__create_mp (const char *path, int cmode, size_t initialsz, int basepe, size_t *chunksizehintp, int *ncidp)

This function was used in the old days with the Cray at NCAR. The Cray is long gone, and this call is supported only for backward compatibility.

Global nc__open_mp (const char *path, int mode, int basepe, size_t *chunksizehintp, int *ncidp)

This function was used in the old days with the Cray at NCAR. The Cray is long gone, and this call is supported only for backward compatibility.

Global NC_FORMAT_64BIT

Saved for compatibility.

Global NC_FORMAT_DAP2

As of 4.4.0, use NC_FORMATX_DAP2

Global NC_FORMAT_DAP4

As of 4.4.0, use NC_FORMATX_DAP4

Global NC_FORMAT_NC3

As of 4.4.0, use NC_FORMATX_NC3

Global NC_FORMAT_NC4

As of 4.4.0, use NC_FORMATX_NC4

Global NC_FORMAT_NC_HDF4

As of 4.4.0, use NC_FORMATX_HDF4

Global NC_FORMAT_NC_HDF5

As of 4.4.0, use NC_FORMATX_NC_HDF5

Global NC_FORMAT_PNETCDF

As of 4.4.0, use NC_FORMATX_PNETCDF

Global NC_FORMAT_UNDEFINED

As of 4.4.0, use NC_FORMATX_UNDEFINED

Global nc_get_varm (int ncid, int varid, const size_t *startp, const size_t *countp, const ptrdiff_t *stridep, const ptrdiff_t *imapp, void *ip)

Use of this family of functions is discouraged, although it will continue to be supported. The reason is the complexity of the algorithm makes its use difficult for users to properly use.

Global nc_inq_base_pe (int ncid, int *pe)

This function was used in the old days with the Cray at NCAR. The Cray is long gone, and this call is supported only for backward compatibility.

Global NC_LOCK

The following flag currently is ignored, but use in nc_open() or nc_create() may someday support use of advisory locking to prevent multiple writers from clobbering a file

Global NC_LONG

required for backward compatibility.

Global NC_MPIPOSIX

As of libhdf5 1.8.13.

Global nc_put_varm (int ncid, int varid, const size_t *startp, const size_t *countp, const ptrdiff_t *stridep, const ptrdiff_t *imapp, const void *op)

Use of this family of functions is discouraged, although it will continue to be supported. The reason is the complexity of the algorithm makes its use difficult for users to properly use.

Global nc_set_base_pe (int ncid, int pe)

This function was used in the old days with the Cray at NCAR. The Cray is long gone, and this call is supported only for backward compatibility.
