gnutls_x509_crt_get_name_constraints: API function
NAME
gnutls_x509_crt_get_name_constraints - API functionSYNOPSIS
#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);
ARGUMENTS
- gnutls_x509_crt_t crt
- should contain a gnutls_x509_crt_t structure
- gnutls_x509_name_constraints_t nc
- The nameconstraints intermediate structure
- unsigned int flags
- zero or GNUTLS_NAME_CONSTRAINTS_FLAG_APPEND
- unsigned int * critical
- the extension status
DESCRIPTION
This function will return an intermediate structure 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_NAME_CONSTRAINTS_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 only the excluded constraints will be appended to the constraints.
Note that nc must be initialized prior to calling this function.
RETURNS
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.SINCE
