Document that passing 0 to a close/destroy function does nothing and returns PSA_SUCCESS. Although this was not written explicitly, the specification strongly suggested that this would return PSA_ERROR_INVALID_HANDLE. While returning INVALID_HANDLE makes sense, it was awkward for a very common programming style where applications can store 0 in a handle variable to indicate that the handle has been closed or has never been open: applications had to either check if (handle != 0) before calling psa_close_key(handle) or psa_destroy_key(handle), or ignore errors from the close/destroy function. Now applications following this style can just call psa_close_key(handle) or psa_destroy_key(handle). |
