int gnutls_x509_crt_get_proxy(gnutls_x509_crt_t cert, unsigned int * critical, int * pathlen, char ** policyLanguage, char ** policy, size_t * sizeof_policy);
ARGUMENTS
gnutls_x509_crt_t cert
should contain a gnutls_x509_crt_t structure
unsigned int * critical
will be non zero if the extension is marked as critical
int * pathlen
pointer to output integer indicating path length (may be
NULL), non-negative values indicate a present pCPathLenConstraint
field and the actual value, -1 indicate that the field is absent.
char ** policyLanguage
output variable with OID of policy language
char ** policy
output variable with policy data
size_t * sizeof_policy
output variable size of policy data
DESCRIPTION
This function will get information from a proxy certificate. It
reads the ProxyCertInfo X.509 extension (1.3.6.1.5.5.7.1.14).
RETURNS
