Typedef Documentation

◆ quarklink_context_t

typedef struct quarklink_context_t quarklink_context_t

Quarklink context.

This struct is ~6.4KB and contains all the resources needed by a user that wants to use Quarklink. All certificates are in PEM format.

Note: User needs to define a quarklink_context_t variable and initialise it by calling quarklink_init. Calls to QuarkLink APIs populate the struct fields, which the user is free to access. Empty fields are set to zero/NULL. After quarklink_init, the available fields are: rootCert, endpoint, port, deviceID After quarklink_enrol, the additional available fields are: deviceCert, iotHubRootCert, iotHubEndpoint, iotHubPort

Enumeration Type Documentation

◆ quarklink_return_t

enum quarklink_return_t
