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.

SEE ALSO

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.
