+The return value is returned in a compound structure:
+\begin{codesample}
+typedef struct {
+    enum {
+        RC_OK,          /* Decoded successfully */
+        RC_WMORE,       /* More data expected, call again */
+        RC_FAIL         /* Failure to decode data */
+    } code;             /* Result code */
+    size_t consumed;    /* Number of bytes consumed */
+} asn_dec_rval_t;
+\end{codesample}
+
+The \code{.code} member specifies the decoding outcome.
+
+\begin{description}[labelindent=\parindent]
+\item[RC\_OK] Decoded successfully and completely
+\item[RC\_WMORE] More data expected, call again
+\item[RC\_FAIL] Failed for good
+\end{description}
+
+The \code{.consumed} member specifies the amount of \code{buffer} data
+that was used during parsing, irrespectively of the \code{.code}.
