Return Codes

Most of the SDK’s API functions return a riotee_rc_t that indicates the status of the transaction.

There are a number of common return codes defined in core/include/riotee.h. Modules can additionally define their own return codes starting at a module-specific offset, which is also defined in core/include/riotee.h.

Long-running interactions with peripherals may be interrupted by a reset or a teardown event. To ensure correct application execution, always check the return codes of such functions for the return values RIOTEE_ERR_RESET and RIOTEE_ERR_TEARDOWN. If a function call failed with one of these return codes, the application can, for example, wait until the capacitor is fully charged with riotee_wait_cap_charged() before trying again.
