D2I_ASN1_SEQUENCE_ANY(3) DragonFly Library Functions Manual
NAME
d2i_ASN1_SEQUENCE_ANY, i2d_ASN1_SEQUENCE_ANY, d2i_ASN1_SET_ANY,
i2d_ASN1_SET_ANY - decode and encode ASN.1 sequences and sets
SYNOPSIS
#include <openssl/asn1.h>
ASN1_SEQUENCE_ANY *
d2i_ASN1_SEQUENCE_ANY(ASN1_SEQUENCE_ANY **val_out,
const unsigned char **der_in, long length);
int
i2d_ASN1_SEQUENCE_ANY(const ASN1_SEQUENCE_ANY *val_in,
unsigned char **der_out);
ASN1_SEQUENCE_ANY *
d2i_ASN1_SET_ANY(ASN1_SEQUENCE_ANY **val_out,
const unsigned char **der_in, long length);
int
i2d_ASN1_SET_ANY(const ASN1_SEQUENCE_ANY *val_in,
unsigned char **der_out);
DESCRIPTION
These functions decode and encode ASN.1 sequences and sets. For details
about the semantics, examples, caveats, and bugs, see ASN1_item_d2i(3).
The type ASN1_SEQUENCE_ANY is defined as STACK_OF(ASN1_TYPE). Whether
such an object represents a sequence or a set is not stored in the object
itself but needs to be remembered separately.
Like for d2i_ASN1_TYPE(3) and i2d_ASN1_TYPE(3), the type of the
individual values contained in the sequence or set is not specified when
calling the functions. It might vary among the members, and it is stored
together with each value in each ASN1_TYPE object contained in the
sequence or set.
RETURN VALUES
d2i_ASN1_SEQUENCE_ANY() returns an ASN1_SEQUENCE_ANY object or NULL if an
error occurs.
i2d_ASN1_SEQUENCE_ANY() returns the number of bytes written or a negative
value if an error occurs.

HISTORY
d2i_ASN1_SEQUENCE_ANY(), i2d_ASN1_SEQUENCE_ANY(), d2i_ASN1_SET_ANY(), and
i2d_ASN1_SET_ANY() first appeared in OpenSSL 1.0.0 and have been
available since OpenBSD 4.9.
