NAME

       asn1rt - ASN.1 runtime support functions

DESCRIPTION

       This  module  is the interface module for the ASN.1 runtime support functions. To encode and decode ASN.1
       types in runtime the functions in this module should be used.

EXPORTS

       decode(Module,Type,Bytes) -> {ok,Value}|{error,Reason}

              Types:

                 Module = Type = atom()
                 Value = Reason = term()
                 Bytes = binary

              Decodes Type from Module from the binary Bytes. Returns {ok,Value} if successful.

       encode(Module,Type,Value)-> {ok,Bytes} | {error,Reason}

              Types:

                 Module = Type = atom()
                 Value = term()
                 Bytes = binary
                 Reason = term()

              Encodes Value of Type defined in the ASN.1 module Module. Returns a possibly nested list of  bytes
              and  or  binaries  if  successful.  To  get as fast execution as possible the encode function only
              performs rudimentary tests that the input Value is a correct  instance  of  Type.  The  length  of
              strings is for example not always checked.

          Note:
              Starting in R16, Bytes is always a binary.

       info(Module) -> {ok,Info} | {error,Reason}

              Types:

                 Module = atom()
                 Info = list()
                 Reason = term()

              info/1  returns  the  version  of  the  asn1 compiler that was used to compile the module. It also
              returns the compiler options that was used.

       utf8_binary_to_list(UTF8Binary) -> {ok,UnicodeList} | {error,Reason}

              Types:

                 UTF8Binary = binary()
                 UnicodeList = [integer()]
                 Reason = term()

              utf8_binary_to_list/1 Transforms a UTF8 encoded binary to a list of integers, where  each  integer
              represents  one character as its unicode value. The function fails if the binary is not a properly
              encoded UTF8 string.

       utf8_list_to_binary(UnicodeList) -> {ok,UTF8Binary} | {error,Reason}

              Types:

                 UnicodeList = [integer()]
                 UTF8Binary = binary()
                 Reason = term()

              utf8_list_to_binary/1 Transforms a list of integers, where each integer represents  one  character
              as its unicode value, to a UTF8 encoded binary.
