gnutls_x509_cidr_to_rfc52803
Api function
Usage
#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 |
Overview
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.
