5.7.1 Creating Opaque Types: NF_DEF_OPAQUE
Create an opaque type. Provide a size and a name.
Usage
INTEGER FUNCTION NF_DEF_OPAQUE(INTEGER NCID, CHARACTER*(*) NAME,
INTEGER SIZE, INTEGER TYPEIDP)
NCID- The groupid where the type will be created. The type may be used
anywhere in the file, no matter what group it is in.
NAME- The name for this type. Must be shorter than NF_MAX_NAME.
SIZE- The size of each opaque object.
TYPEIDP- Pointer where the new typeid for this type is returned. Use this
typeid when defining variables of this type with NF_DEF_VAR.
Errors
NF_NOERR- No error.
NF_EBADTYPEID- Bad typeid.
NF_EBADFIELDID- Bad fieldid.
NF_EHDFERR- An error was reported by the HDF5 layer.
Example
This example is from nf_test/ftst_vars3.F.
C Create the opaque type.
retval = nf_def_opaque(ncid, opaque_size, opaque_type_name,
& opaque_typeid)
if (retval .ne. nf_noerr) call handle_err(retval)
