```
+A header containing these wrappers should be auto-generated using a template and annotations to the input and output parameters to the PSA API. This will look something like the following:
+```c
+MBEDTLS_PSA_SHARED_BUFFER(input, input_length)
+MBEDTLS_PSA_SHARED_BUFFER(output, output_size)
+psa_status_t psa_aead_update(psa_aead_operation_t *operation,
+ const uint8_t *input,
+ size_t input_length,
+ uint8_t *output,
+ size_t output_size,
+ size_t *output_length);
+```
+The `MBEDTLS_PSA_SHARED_BUFFER()` annotation expands to an empty expression but can be parsed by the wrapper generation script, which generates a new header file with the wrappers.
