Fortran90 Interface: h5pset_family_offset_f
SUBROUTINE h5pset_family_offset_f(prp_id, offset, hdferr)
INTEGER(HID_T), INTENT(IN) :: prp_id ! Property list identifier
INTEGER(HSIZE_T), INTENT(IN) :: offset ! Offset in bytes
INTEGER, INTENT(OUT) :: hdferr ! Error code
! 0 on success and -1 on failure
END SUBROUTINE h5pset_family_offset_f
IN: File access property list identifier
IN: Offset in bytes within the HDF5 file
H5P_SET_FAMILY_OFFSET sets the offset property in the file access property list fapl_id so that the user application can retrieve a file handle for low-level access to a particular member of a family of files. The file handle is retrieved with a separate call to H5F_GET_VFD_HANDLE (or, in special circumstances, to H5FD_GET_VFD_HANDLE; see Virtual File Layer and List of VFL Functions in HDF5 Technical Notes).
The value of offset is an offset in bytes from the beginning of the HDF5 file, identifying a user-determined location within the HDF5 file. The file handle the user application is seeking is for the specific member-file in the associated family of files to which this offset is mapped.
Use of this function is only appropriate for an HDF5 file written as a family of files with the FAMILY file driver.
Returns a non-negative value if successful; otherwise returns a negative value.
