       The proxypolicy set of data structures and functions provides an interface to generating a
       PROXYPOLICY structure which is maintained as a field in the PROXYCERTINFO structure, and
       ultimately gets written to a DER encoded string.

       See Also:
           Further Information about proxy policies is available in the X.509 Proxy Certificate
           Profile document.

Function Documentation

   ASN1_METHOD* PROXYPOLICY_asn1_meth ()
       Creates an ASN1_METHOD structure, which contains pointers to routines that convert any
       PROXYPOLICY structure to its associated ASN1 DER encoded form and vice-versa.

       Returns:
           the ASN1_METHOD object

       References d2i_PROXYPOLICY(), i2d_PROXYPOLICY(), PROXYPOLICY_free(), and
       PROXYPOLICY_new().

   PROXYPOLICY* PROXYPOLICY_new ()
       Allocates and initializes a new PROXYPOLICY structure.

       Returns:
           pointer to the new PROXYPOLICY

   void PROXYPOLICY_free (PROXYPOLICY *policy)
       Frees a PROXYPOLICY.

       Parameters:
           policy the proxy policy to free

   PROXYPOLICY* PROXYPOLICY_dup (PROXYPOLICY *policy)
       Makes a copy of the proxypolicy - this function allocates space for a new PROXYPOLICY, so
       the returned PROXYPOLICY must be freed when its no longer needed.

       Parameters:
           policy the proxy policy to copy

       Returns:
           the new PROXYPOLICY

       References d2i_PROXYPOLICY(), and i2d_PROXYPOLICY().

   int PROXYPOLICY_cmp (const PROXYPOLICY *a, const PROXYPOLICY *b)
       Compares two PROXYPOLICY structs for equality This function first compares the policy
       language numeric id's, if they're equal, it then compares the two policies.

       Returns:
           0 if equal, nonzero if not

   int PROXYPOLICY_print (BIO *bp, PROXYPOLICY *policy)
       Prints the PROXYPOLICY struct using the BIO stream.

       Parameters:
           bp the BIO stream to print to
           policy the PROXYPOLICY to print

       Returns:
           1 on success, 0 on error

   int PROXYPOLICY_print_fp (FILE *fp, PROXYPOLICY *policy)
       Prints the PROXYPOLICY to the file stream FILE*.

       Parameters:
           fp the FILE* stream to print to
           policy the PROXYPOLICY to print

       Returns:
           number of bytes printed, -2 or -1 on error

       References PROXYPOLICY_print().

   int PROXYPOLICY_set_policy_language (PROXYPOLICY *policy, ASN1_OBJECT *policy_language)
       Sets the policy language of the PROXYPOLICY.

       Parameters:
           policy the PROXYPOLICY to set the policy language of
           policy_language the policy language to set it to

       Returns:
           1 on success, 0 on error

   ASN1_OBJECT* PROXYPOLICY_get_policy_language (PROXYPOLICY *policy)
       Gets the policy language of the PROXYPOLICY.

       Parameters:
           policy the proxy policy to get the policy language of

       Returns:
           the policy language as an ASN1_OBJECT

   int PROXYPOLICY_set_policy (PROXYPOLICY *proxypolicy, unsigned char *policy, intlength)
       Sets the policy of the PROXYPOLICY.

       Parameters:
           proxypolicy the proxy policy to set the policy of
           policy the policy to set it to
           length the length of the policy

       Returns:
           1 on success, 0 on error

   unsigned char* PROXYPOLICY_get_policy (PROXYPOLICY *policy, int *length)
       Gets the policy of a PROXYPOLICY.

       Parameters:
           policy the PROXYPOLICY to get the policy of
           length the length of the returned policy - this value gets set by this function

       Returns:
           the policy

   int i2d_PROXYPOLICY (PROXYPOLICY *a, unsigned char **pp)
       Converts a PROXYPOLICY from its internal structure to a DER encoded form.

       Parameters:
           a the PROXYPOLICY to convert
           pp the buffer to put the DER encoding in

       Returns:
           the length of the DER encoding in bytes

   PROXYPOLICY* d2i_PROXYPOLICY (PROXYPOLICY **a, unsigned char **pp, longlength)
       Converts the PROXYPOLICY from its DER encoded form to an internal PROXYPOLICY structure.

       Parameters:
           a the PROXYPOLICY struct to set
           pp the DER encoding to get the PROXYPOLICY from
           length the length of the DER encoding

       Returns:
           the resulting PROXYPOLICY in its internal structure form - this variable has been
           allocated using _new routines, so it needs to be freed once its no longer used
