NAME
gnutls_x509_crq_get_basic_constraints - get certificate’s basic
constraints
SYNOPSIS
#include <gnutls/x509.h>
int gnutls_x509_crq_get_basic_constraints(gnutls_x509_crq_t cert,
unsigned int * critical, int * ca, int * pathlen);
ARGUMENTS
gnutls_x509_crq_t cert
should contain a gnutls_x509_crq_t structure
unsigned int * critical
will be non zero if the extension is marked as critical
int * ca pointer to output integer indicating CA status, may be
NULL, value is 1 if the certificate CA flag is set, 0
otherwise.
int * pathlen
pointer to output integer indicating path length (may be
NULL), non-negative values indicate a present
pathLenConstraint field and the actual value, -1 indicate
that the field is absent.
DESCRIPTION
This function will read the certificate’s basic constraints, and return
the certificates CA status. It reads the basicConstraints X.509
extension (2.5.29.19).
RETURN VALUE
If the certificate is a CA a positive value will be returned, or zero
if the certificate does not have CA flag set. A negative value may be
returned in case of errors. If the certificate does not contain the
basicConstraints extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will
be returned.
SINCE
2.8.0
