5.5.4 Learn About a Compound Type: NF90_INQ_COMPOUND
Get the number of fields, length in bytes, and name of a compound
type.
In addtion to the NF90_INQ_COMPOUND function, three additional functions
are provided which get only the name, size, and number of fields.
Usage
function nf90_inq_compound(ncid, xtype, name, size, nfields)
integer, intent(in) :: ncid
integer, intent(in) :: xtype
character (len = *), intent(out) :: name
integer, intent(out) :: size
integer, intent(out) :: nfields
integer :: nf90_inq_compound
function nf90_inq_compound_name(ncid, xtype, name)
integer, intent(in) :: ncid
integer, intent(in) :: xtype
character (len = *), intent(out) :: name
integer :: nf90_inq_compound_name
function nf90_inq_compound_size(ncid, xtype, size)
integer, intent(in) :: ncid
integer, intent(in) :: xtype
integer, intent(out) :: size
integer :: nf90_inq_compound_size
function nf90_inq_compound_nfields(ncid, xtype, nfields)
integer, intent(in) :: ncid
integer, intent(in) :: xtype
integer, intent(out) :: nfields
integer :: nf90_inq_compound_nfields
NCID- The ID of any group in the file that contains the compound type.
XTYPE- The typeid for this compound type, as returned by NF90_DEF_COMPOUND, or
NF90_INQ_VAR.
NAME- Character array which will get the name of the compound type. It will
have a maximum length of NF90_MAX_NAME.
SIZEP- The size of the compound type in bytes will be put here.
NFIELDSP- The number of fields in the compound type will be placed here.
Return Codes
NF90_NOERR- No error.
NF90_EBADID- Couldn't find this ncid.
NF90_ENOTNC4- Not a netCDF-4/HDF5 file.
NF90_ESTRICTNC3- A netCDF-4/HDF5 file, but with CLASSIC_MODEL. No user defined types
are allowed in the classic model.
NF90_EBADTYPE- This type not a compound type.
NF90_EBADTYPEID- Bad type id.
NF90_EHDFERR- An error was reported by the HDF5 layer.
