                   const void *ider,
                   int ider_len,
                   char *errorDescription);

The DER vector must contain the encoding string of the whole STRUCTURE . If an error occurs during the decoding procedure, the *STRUCTURE is deleted and set equal to NULL.

This function is deprecated and may just be an alias to asn1_der_decoding in future versions. Use asn1_der_decoding() instead.
