! NOTES
!
!  (A) C_LOC and character strings according to the Fortran 2003 standard:
!
!  15.1.2.5 C_LOC(X)
!
!  Argument. X shall either
!
!  (1) have interoperable type and type parameters and be
!    (a) a variable that has the TARGET attribute and is interoperable,
!    (b) an allocated allocatable variable that has the TARGET attribute
!        and is not an array of zero size, or
!    (c) an associated scalar pointer, or
!  (2) be a nonpolymorphic scalar, have no length type parameters, and be
!    (a) a nonallocatable, nonpointer variable that has the TARGET attribute,
!    (b) an allocated allocatable variable that has the TARGET attribute, or
!    (c) an associated pointer.
!
!  - When X is a character, for interoperability the standard is:
!
!  15.2.1 Interoperability of intrinsic types
!
!  ...if the type is character, interoperability also requires that the length type parameter
!  be omitted or be specified by an initialization expression whose value is one.
!
!  THEREFORE compilers that have not extended the standard  require
!
!  CHARACTER(LEN=1), TARGET :: chr
!  or
!  CHARACTER, TARGET :: chr
!
!  (B)
!                         *** IMPORTANT ***
!  If you add a new H5A function you must add the function name to the
!  Windows dll file 'hdf5_fortrandll.def.in' in the fortran/src directory.
!  This is needed for Windows based operating systems.

! HISTORY
!  Explicit Fortran interfaces are added for
!  called C functions (it is needed for Windows
!  port).  February 27, 2001
!
!  dims parameter was added to make code portable;
!  Aprile 4, 2001
!
!  Changed buf intent to INOUT to be consistant
!  with how the C functions handles it. The pg
!  compiler will return 0 if a buf value is not set.
!  February, 2008
!
! NOTES
!  This function is overloaded to write INTEGER,
!  REAL, DOUBLE PRECISION and CHARACTER buffers
!  up to 7 dimensions.

!****s* H5A (F03)/H5Aread_f_F03
!
! NAME
!  H5Aread_f_F03
!
! PURPOSE
!  Reads an attribute.
!
! Inputs:
!  attr_id     - Attribute identifier
!  memtype_id  - Attribute datatype identifier  (in memory)
!
! Outputs:
!  buf 	       - Data buffer; may be a scalar or an array
!  hdferr      - Returns 0 if successful and -1 if fails

! HISTORY
!  Explicit Fortran interfaces are added for
!  called C functions (it is needed for Windows
!  port).  February 27, 2001
!
!  dims parameter was added to make code portable;
!  Aprile 4, 2001
!
!  Changed buf intent to INOUT to be consistant
!  with how the C functions handles it. The pg
!  compiler will return 0 if a buf value is not set.
!  February, 2008
!
! NOTES
!  This function is overloaded to write INTEGER,
!  REAL, DOUBLE PRECISION and CHARACTER buffers
!  up to 7 dimensions.
! Fortran2003 Interface:
!!  SUBROUTINE H5Aread_f(attr_id, memtype_id, buf, hdferr) 
!!    INTEGER(HID_T)  , INTENT(IN)    :: attr_id
!!    INTEGER(HID_T)  , INTENT(IN)    :: memtype_id
!!    TYPE(C_PTR)     , INTENT(INOUT) :: buf
!!    INTEGER         , INTENT(OUT)   :: hdferr
