internal¶

As the name suggests, the functionality in this module is meant for internal package use only.

class cyclonedds.internal.DDS(reference)[source]¶

Common class for all DDS related classes. This class enables the c_call magic.

Parameters: reference (int) –
Return type: None

cyclonedds.internal.load_cyclonedds()[source]¶

Internal method to load the Cyclone DDS Dynamic Library. Handles platform specific naming/configuration.

Return type: ctypes.CDLL

@cyclonedds.internal.c_call[source]¶: Decorator. Convert a function into call into the class associated dll.

cyclonedds.internal.c_callable(return_type, argument_types)[source]¶

Decorator. Make a C function type based on python type annotations.

Return type: ctypes.CFUNCTYPE
