pdcomm_opcua_handle

Typedef

Opaque, library-local handle of a client, a server or a buffer.

typedef uint64_t pdcomm_opcua_handle

Declared in: #include <pdcomm/opcua/pdcomm_opcua.h>

Zero is never a valid handle. Functions that return a handle write zero to their output first, so the output is zero after any failure (and after #PDCOMM_OPCUA_EMPTY) once the output pointer itself is valid.
