Rhapsody / manual code in C/C++

These environments are also completely supported. aadl2glueC creates the necessary C code that reads and writes the relevant ASN.1 messages, utilizing asn1Scc's [15] "bridge" data structures in C that contain the semantically equivalent information. This considerably lessens the effort required to access the message marshalling routines from within Rhapsody (or manually written C/C++ code), as the user has access to simple standalone^3.3 C data structures for all the messages exchanged.

Table 2.3: From ASN.1 to C

INTEGER	long
REAL	double
BOOLEAN	int
OCTET STRING	char[x] plus an int xyz_len variable
ENUMERATED	long
SEQUENCE OF	typename[x] plus an int xyz_len variable
SEQUENCE	struct ...

Table 2.3 describes the mapping from ASN.1 entities to the C "bridge" variables.
