1. ASN.1 to C or C++ or IDL compiler Snacc is short for "Sample Neufeld ASN.1 to C Compiler" and ASN.1 stands for Abstract Syntax Notation One (ITU-T X.208/ISO 8824). Snacc supports a subset of ASN.1 1988. If you need features of ASN.1 1992 or later, snacc is not for you. Given an ASN.1 source file(s) snacc can produce: 1. C routines for BER encoding, decoding, printing and freeing. 2. C++ routines for BER encoding, decoding, and printing. 3. A type table that can be used with C driver routines for BER encoding, decoding, printing and freeing. If you want to build snacc based applications, you want to install the libsnacc-dev package, too. Your application will then depend on the snacc libraries, you find in the libsnacc0 package.
