Locks a datatype

Procedure:

H5T_LOCK (dtype_id)

Signature:

<pre><code class="language-c">herr_t H5Tlock( hid_t dtype_id )</code></pre>

Parameters:
hid_t dtype_id    IN: Identifier of datatype to lock

Description:

H5T_LOCK locks the datatype specified by the dtype_id identifier, making it read-only and non-destructible. This is normally done by the library for predefined datatypes so the application does not inadvertently change or delete a predefined type. Once a datatype is locked it can never be unlocked.

Returns:

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