.SH NAME

gnutls_x509_ext_import_name_constraints \- API function

.SH SYNOPSIS

.B #include <gnutls/x509-ext.h>

.sp

.BI "int gnutls_x509_ext_import_name_constraints(const gnutls_datum_t * " ext ", gnutls_x509_name_constraints_t " nc ", unsigned int " flags ");"

.SH ARGUMENTS

.IP "const gnutls_datum_t * ext" 12

a DER encoded extension

.IP "gnutls_x509_name_constraints_t nc" 12

The nameconstraints

.IP "unsigned int flags" 12

zero or \fBGNUTLS_NAME_CONSTRAINTS_FLAG_APPEND\fP

.SH "DESCRIPTION"

This function will return an intermediate type containing

the name constraints of the provided NameConstraints extension. That

can be used in combination with \fBgnutls_x509_name_constraints_check()\fP

to verify whether a server's name is in accordance with the constraints.

When the  \fIflags\fP is set to \fBGNUTLS_NAME_CONSTRAINTS_FLAG_APPEND\fP, then if 

the  \fInc\fP type is empty this function will behave identically as if the flag was not set.

Otherwise if there are elements in the  \fInc\fP 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  \fInc\fP must be initialized prior to calling this function.

.SH "RETURNS"

On success, \fBGNUTLS_E_SUCCESS\fP (0) is returned, \fBGNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE\fP

if the extension is not present, otherwise a negative error value.

.SH "SINCE"

3.3.0
