PER Runtime Library Functions.

Detailed Description

The ASN.1 Packed Encoding Rules (PER) runtime library contains the low-level constants, types, and functions that are assembled by the compiler to encode/decode more complex structures. The PER low-level C encode/decode functions are identified by their prefixes: pe_ for PER encode, pd_ for PERdecode, and pu_ for PER utility functions.
