uint32 C.encode memory chunk(const char ∗ in buf , uint32 in len, char ∗ out buf ,
uint32 out len)
encodes the memory chunk starting at in buf with
size in len into the buffer starting at out buf with size
out len. The function returns actual length of the
encoded chunk which may be smaller than out len. If
the output buffer is too small for the encoded data
the failure flag will be set (see below). Note: The
output data is slightly longer than the input data due
to padding and header data.
uint32 C.decode memory chunk(const char ∗ in buf , uint32 in len, char ∗ out buf ,
uint32 out len)
decodes a memory chunk. The meaning of the parameters
and the return value is the same as in the
previous function.
streambuf ∗ C.get src stream( ) returns the current source stream.
void
C.set src stream(streambuf ∗ src stream, bool own stream = false)
sets the source stream (cf. constructor).
void C.set src file(const char ∗ file name)
sets a file as source stream.
streambuf ∗ C.get tgt stream( ) returns the current target stream.
void
void
void
C.set tgt stream(streambuf ∗ tgt stream, bool own Stream = false)
C.set tgt file(const char ∗ file name)
C.reset(bool keep key = true)
sets the target stream (cf. constructor).
sets a file as target stream.
puts C in the same state as the default constructor.
If keep key is false the key is set to the empty key. In
any case the initialization vector is set to nil.
bool C.failed( ) returns true if an error occured.
bool C.finished( ) returns true if the coding is finished.
string C.get description( ) provides a description for C.
Additional Operations
uint16 C.get default key size( )
returns the default key size.
