# asn1\_decode\_simple\_ber(3)

API function

## NAME

asn1\_decode\_simple\_ber - API function

## SYNOPSIS

**#include \<libtasn1.h\>**

**int asn1\_decode\_simple\_ber(unsigned int** *etype***, const unsigned char \*** *der***, unsigned int** *\_der\_len***, unsigned char \*\*** *str***, unsigned int \*** *str\_len***, unsigned int \*** *ber\_len***);**

## ARGUMENTS

- unsigned int etype

  The type of the string to be encoded (ASN1\_ETYPE\_)

- const unsigned char \* der

  the encoded string

- unsigned int \_der\_len

  the bytes of the encoded string

- unsigned char \*\* str

  a pointer to the data

- unsigned int \* str\_len

  the length of the data

- unsigned int \* ber\_len

  the total length occupied by BER (may be **NULL**)

## DESCRIPTION

Decodes a BER encoded type. The output is an allocated value of the data. This decodes BER STRINGS only. Other types are decoded as DER.

## RETURNS

**ASN1\_SUCCESS** if successful or an error value.
