BER Runtime Library Functions.

Detailed Description

The ASN.1 Basic Encoding Rules (BER) Runtime Library contains the low-level constants, types, and functions that are assembled by the compiler to encode/decode more complex structures.


Modules

 BER/DER C Decode Functions.
 BER/DER C File Functions.
