NAME

       gss_decapsulate_token - API function

SYNOPSIS

       #include <gss.h>

       OM_uint32  gss_decapsulate_token(gss_const_buffer_t  input_token, gss_const_OID token_oid,
       gss_buffer_t output_token);

ARGUMENTS

       gss_const_buffer_t input_token
                   (buffer, opaque, read) Buffer with GSS-API context token.

       gss_const_OID token_oid
                   (Object ID, read) Expected object identifier of token.

       gss_buffer_t output_token
                   (buffer, opaque, modify) Decapsulated token data;
                     caller must release with gss_release_buffer().

DESCRIPTION

       Remove the mechanism-independent token header  from  an  initial  GSS-API  context  token.
       Unwrap  a  buffer  in  the  mechanism-independent  token  format.   This is the reverse of
       gss_encapsulate_token().  The translation is loss-less, all data is preserved as is.  This
       function is standardized in RFC 6339.

RETURN VALUE

       `GSS_S_COMPLETE`:  Indicates  successful  completion,  and  that  output  parameters holds
       correct information.

       `GSS_S_DEFECTIVE_TOKEN`: Means  that  the  token  failed  consistency  checks  (e.g.,  OID
       mismatch or ASN.1 DER length errors).

       `GSS_S_FAILURE`:  Indicates  that  decapsulation  failed  for  reasons  unspecified at the
       GSS-API level.
