5.4 Learn About an User Defined Type: NF_INQ_USER_TYPE
Given an ncid and a typeid, get the information about a user defined
type. This function will work on any user defined type, whether
compound, opaque, enumeration, or variable length array.
Usage
INTEGER FUNCTION NF_INQ_USER_TYPE(INTEGER NCID, INTEGER XTYPE,
CHARACTER*(*) NAME, INTEGER SIZE, INTEGER BASE_NF_TYPE,
INTEGER NFIELDS, INTEGER CLASS)
NCID- The ncid for the group containing the user defined type.
XTYPE- The typeid for this type, as returned by NF_DEF_COMPOUND,
NF_DEF_OPAQUE, NF_DEF_ENUM, NF_DEF_VLEN, or NF_INQ_VAR.
NAME- The name of the user defined type will be copied here. It
will be NF_MAX_NAME bytes or less.
SIZE- The size of the user defined type will be copied here.
BASE_NF_TYPE- The base typeid will be copied here for vlen and enum types.
NFIELDS- The number of fields will be copied here for enum and compound types.
CLASS- The class of the user defined type, NF_VLEN, NF_OPAQUE, NF_ENUM, or
NF_COMPOUND, will be copied here.
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_types2.F.
C Check the type.
retval = nf_inq_user_type(ncid, typeids(1), name_in, size_in,
& base_type_in, nfields_in, class_in)
if (retval .ne. nf_noerr) call handle_err(retval)
