NAME

       gnutls_x509_crt_get_name_constraints - API function

SYNOPSIS

       #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 type

       gnutls_x509_name_constraints_t nc
                   The nameconstraints intermediate type

       unsigned int flags
                   zero or GNUTLS_NAME_CONSTRAINTS_FLAG_APPEND

       unsigned int * critical
                   the extension status

DESCRIPTION

       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_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

       3.3.0
