       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

   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

   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

   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, int length)
       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, long
       length)
       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
