Clear all resources alloctated in an ua_applicationdescription struct.
Frees allocated memory like arrays and resets numeric values. The ua_applicationdescription struct itself is not freed and must be freed by the caller if required. This function always succeeds for a valid ua_applicationdescription struct, that was validly decoded, initilized by ua_applicationdescription_init or created with ua_applicationdescription_copy.

Compare two ua_applicationdescription structs.
Compares the content of the ua_applicationdescription struct a
to the content of the ua_applicationdescription struct b
. If a
is smaller than b
, an integer less than zero is returned, if a
is bigger than b
, an integer greater than zero is returned. If both structs are equal zero is returned.
This function creates a total order on ua_applicationdescription structs, so it is well suited to not only determine equality, but also sort multiple instances of this struct.

Create a copy of a ua_applicationdescription struct.
Copy all fields from struct ua_applicationdescription src
to dst
. Creates a deep copy so all content is recusively copied and both src
and dst
can be used and must be freed separately.
dst
is not cleared before the copy operation, so it must not have any allocated data. It may or may not be initilized by the caller before copy.

Initialize an ua_applicationdescription struct with a valid value.
After initialization the fields of the struct are set to valid and consistent values and can safley be accessed. An initialized ua_applicationdescription struct can also be passed to ua_applicationdescription_compare, ua_applicationdescription_copy and ua_applicationdescription_clear. This function will always succeed as long as an ua_applicationdescription struct is passed to it.

Resize the discovery_urls array of a ua_applicationdescription struct.
Depending on new_len
and the current size of the array, the array will be created, increased, decreased or deleted. In case array members are removed these are cleared properly, new array members are initialized with zero.
new_len | New length of the discovery_urls array in number of members. |
application_type |
The type of application.
application_uri |
The globally unique identifier for the application instance.
This URI is used as ServerUri in Services if the application is a Server.
discovery_profile_uri |
A URI that identifies the discovery profile supported by the URLs provided.
This field is not used if the ApplicationType is client.
discovery_urls |
A list of URLs for the discovery Endpoints provided by the application.
If the ApplicationType is Client, this field shall contain an empty list.
gateway_server_uri |
A URI that identifies the Gateway Server associated with the DiscoveryUrls.
This value is not specified if the Server can be accessed directly.
This field is not used if the ApplicationType is Client.
