asn1_der_decoding - API function
SYNOPSIS¶
#include <libtasn1.h>

* ider, int len, char *
errorDescription);
ARGUMENTS¶
- ASN1_TYPE * element
- pointer to an ASN1 structure.
- const void * ider
- vector that contains the DER encoding.
- int len
- number of bytes of *ider:
ider[0]..ider[len-1].
- char * errorDescription
- null-terminated string contains details when an error

ELEMENT is deleted
and set equal to
ASN1_TYPE_EMPTY.

ASN1_SUCCESS if DER encoding OK,
