Name: H5Tlock

Signature:

herr_t H5Tlock(hid_t type_id )

Purpose:

Locks a datatype.

Description:

H5Tlock locks the datatype specified by the type_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.

Parameters:

hid_t type_id

Identifier of datatype to lock.

Returns:

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

Fortran90 Interface:

None.
