Name: H5Idec_type_ref
Signature:
  int `H5Idec_type_ref`( H5I_type_t `type` )
Purpose:
  Decrements the reference count on an identifier type.
Description:
  `H5Idec_type_ref` decrements the reference count on an identifier type. The reference count is used by the library to indicate when an identifier type can be destroyed. If the reference count reaches zero, this function will destroy it.

  The `type` parameter is the identifier for the identifier type whose reference count is to be decremented. This identifier must have been created by a call to `H5Iregister_type`.

Parameters:

H5I_type_t `type` | IN: The identifier of the type whose reference count is to be decremented

Returns:
  Returns the current reference count on success, negative on failure.
Fortran90 Interface:
  None.
