Commits a transient datatype to a file, creating a new named datatype.

This function is deprecated in favor of the function H5T_COMMIT2.


H5T_COMMIT1(loc_id, name, dtype_id)


herr_t H5Tcommit1( hid_t loc_id, const char * name, hid_t dtype_id )

SUBROUTINE h5tcommit_f(loc_id, name, type_id, hdferr) 
  INTEGER(HID_T), INTENT(IN) :: loc_id  ! File or group identifier 
  CHARACTER(LEN=*), INTENT(IN) :: name  ! Datatype name within file or group
  INTEGER(HID_T), INTENT(IN) :: type_id ! Datatype identifier 
  INTEGER, INTENT(OUT) :: hdferr        ! Error code
                                        ! 0 on success and -1 on failure
END SUBROUTINE h5tcommit_f

hid_t loc_idIN: File or group identifier
const char * name    IN: Name given to committed datatype
hid_t dtype_idIN: Identifier of datatype to be committed and, upon function’s return, identifier for the committed datatype


H5Tcommit1 commits the transient datatype (not immutable) to a file, turning it into a named datatype.

The datatype dtype_id is committed as a named datatype at the location loc_id, which is either a file or group identifier, with the name name.

name can be a relative path based at loc_id or an absolute path from the root of the file. Use of this function requires that any intermediate groups specified in the path already exist.

As is the case for any object in a group, the length of the name of a named datatype is not limited.

See H5Tcommit_anon for a discussion of the differences between H5Tcommit and H5Tcommit_anon.

This function will not accept a datatype that cannot actually hold data. This currently includes compound datatypes with no fields and enumerated datatypes with no members.


Returns a non-negative value if successful; otherwise returns a negative value.


Coming Soon!

Release    C
1.8.0The function H5Tcommit renamed to H5Tcommit1 and deprecated in this release.
1.8.7Function modified in this release to reject datatypes that will not accomodate actual data, such as a compound datatype with no fields or an enumerated datatype with no members.
