gnutls_x509_crq_get_basic_constraints - API function
#include <gnutls/x509.h>
int gnutls_x509_crq_get_basic_constraints(gnutls_x509_crq_t crq,
unsigned int * critical, unsigned int * ca, int * pathlen);
gnutls_x509_crq_t crq
should contain a gnutls_x509_crq_t type
unsigned int * critical
will be non-zero if the extension is marked as critical
unsigned 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 error codes indicate a present
pathLenConstraint field and the actual value, -1 indicate
that the field is absent.
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).
If the certificate is a CA a positive value will be returned, or (0)
if the certificate does not have CA flag set. A negative error code
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.
