gnutls_x509_crt_get_name_constraints - API function
#include <gnutls/x509.h>
int gnutls_x509_crt_get_name_constraints(gnutls_x509_crt_t crt,
gnutls_x509_name_constraints_t nc, unsigned int flags, unsigned
int * critical);
gnutls_x509_crt_t crt
should contain a gnutls_x509_crt_t type
gnutls_x509_name_constraints_t nc
The nameconstraints intermediate type
unsigned int flags
zero or GNUTLS_EXT_FLAG_APPEND
unsigned int * critical
the extension status
This function will return an intermediate type containing the
name constraints of the provided CA certificate. That structure
can be used in combination with
gnutls_x509_name_constraints_check() to verify whether a server's
name is in accordance with the constraints.
When the flags is set to GNUTLS_EXT_FLAG_APPEND, then if the nc
structure is empty this function will behave identically as if
the flag was not set. Otherwise if there are elements in the nc
structure then the constraints will be merged with the existing
constraints following RFC5280 p6.1.4 (excluded constraints will
be appended, permitted will be intersected).
Note that nc must be initialized prior to calling this function.
On success, GNUTLS_E_SUCCESS (0) is returned,
GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE if the extension is not
present, otherwise a negative error value.
