Gets information about an attribute
Procedure:
H5LT_GET_ATTRIBUTE_INFO (loc_id, obj_name, attr_name, dims, type_class, type_size)
Signature:
herr_t H5LTget_attribute_info( hid_t loc_id, const char *obj_name, const char *attr_name, hsize_t *dims, H5T_class_t*type_class, size_t *type_size )
subroutine h5ltget_attribute_info_f(loc_id, dset_name, attr_name, &
dims, type_class, type_size, errcode)
implicit none
integer(HID_T), intent(IN) :: loc_id ! file or group identifier
character(LEN=*), intent(IN) :: dset_name ! name of the dataset
character(LEN=*), intent(IN) :: attr_name ! name of the attribute
integer(HSIZE_T),dimension(*),intent(INOUT):: dims
! dimensions
integer, intent(INOUT) :: type_class ! type class
integer(SIZE_T), intent(INOUT) :: type_size ! type size
integer :: errcode ! error code
end subroutine h5ltget_attribute_info_f
Parameters:
hid_t loc_id | IN: Identifier of the object ( dataset or group) to read the attribute from |
const char * obj_name | IN: The name of the object that the attribute is attached to |
const char * attr_name | IN: The attribute name |
hsize_t * dims | OUT: The dimensions of the attribute |
H5T_class_t * type_class | OUT: The class identifier. H5T_class_t is defined in H5Tpublic.h. For a list of valid class types see: H5T_GET_CLASS |
size_t * type_size | OUT: The size of the datatype in bytes |
Description:
H5LT_GET_ATTRIBUTE_INFO gets information about an attribute named attr_name
attached to the object specified by the name obj_name.
Returns:
Returns a non-negative value if successful; otherwise returns a negative value.
Example:
H5T_class_t type_class;
size_t type_size;
hsize_t dims[0];
...
status = H5LTget_attribute_info( file_id, "/", STRNAME, dims, &type_class, &type_size);
if ( type_class == H5T_STRING ) {
printf ("Attribute is a string.\n");
printf ("String size: %i\n", type_size);
