asn1_expand_octet_string - API function

#include <libtasn1.h>

int asn1_expand_octet_string(asn1_node_const definitions, asn1_node * element, const char * octetName, const char * objectName);

ASN1 definitions
pointer to an ASN1 structure
name of the OCTECT STRING field to expand.
name of the OBJECT IDENTIFIER field to use to define the type for expansion.

Expands an "OCTET STRING" element of a structure created from a DER decoding process (the asn1_der_decoding() function). The type used for expansion is the first one following the definition of the actual value of the OBJECT IDENTIFIER indicated by OBJECTNAME.

ASN1_SUCCESS if substitution OK, ASN1_ELEMENT_NOT_FOUND if objectName or octetName are not correct, ASN1_VALUE_NOT_VALID if it wasn't possible to find the type to use for expansion, or other errors depending on DER decoding.
