int BigNumber::marshal (  unsigned char **  pp  )  const [virtual, inherited]

This function creates a serialized representation of the object, which is returned through the argument pp. This must be overridden by the concrete derived class.

void * BigNumber::unmarshal (  void *  bogus, unsigned char **  pp, long  length )  [virtual, inherited]

This function takes a serialized representation of the object and recreates the object representation. This must be overridden by the concrete derived class. Parameters: bogus  Included for compatibility with OpenSSL ASN.1 macros pp  Serialized form of the data length  Number of bytes of pp to unmarshal Returns: success or failure of the unmarshalling Implements CODEX_ASN1::Base.
