NAME

       gnutls_x509_cidr_to_rfc5280 - API function

SYNOPSIS

       #include <gnutls/x509.h>

       int gnutls_x509_cidr_to_rfc5280(const char * cidr, gnutls_datum_t * cidr_rfc5280);

ARGUMENTS

       const char * cidr
                   CIDR in RFC4632 format (IP/prefix), null-terminated

       gnutls_datum_t * cidr_rfc5280
                   CIDR range converted to RFC5280 format

DESCRIPTION

       This  function  will convert text CIDR range with prefix (such as '10.0.0.0/8') to RFC5280
       (IP address in network byte order followed by its network mask).  Works for both IPv4  and
       IPv6.

       The  resulting  object  is  directly  usable for IP name constraints usage, for example in
       functions                  gnutls_x509_name_constraints_add_permitted                   or
       gnutls_x509_name_constraints_add_excluded.

       The data in datum needs to be deallocated using gnutls_free().

RETURNS

       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.

SINCE

       3.5.4
