MODULE SUMMARY

ASN.1 runtime support functions

DESCRIPTION

Warning

All functions in this module are deprecated and will be removed in a future release.

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.

Use Module:decode(Type, Bytes) instead of this function.

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 binary if successful. To get as fast execution as possible, the encode function performs only the rudimentary test that input Value is a correct instance of Type. For example, the length of strings is not always checked.

Use Module:encode(Type, Value) instead of this function.

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

Types:

Module = atom()

Info = list()

Reason = term()

Returns the version of the ASN.1 compiler that was used to compile the module. It also returns the compiler options that were used.

Use Module:info() instead of this function.

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

Types:

UTF8Binary = binary()

UnicodeList = [integer()]

Reason = term()

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.

Use unicode:characters_to_list/1 instead of this function.

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

Types:

UnicodeList = [integer()]

UTF8Binary = binary()

Reason = term()

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

Use unicode:characters_to_binary/1 instead of this function.
