NAME
gnutls_x509_crt_get_ca_status - This function returns the certificate CA status
SYNOPSIS
#include <gnutls/x509.h>
int gnutls_x509_crt_get_ca_status(gnutls_x509_crt_t cert, unsigned int * critical);
ARGUMENTS
| gnutls_x509_crt_t cert | should contain a gnutls_x509_crt_t structure |
| unsigned int * critical | will be non zero if the extension is marked as critical |
DESCRIPTION
This function will return certificates CA status, by reading the basicConstraints X.509 extension (2.5.29.19). If the certificate is a CA a positive value will be returned, or zero if the certificate does not have CA flag set.
Use gnutls_x509_crt_get_basic_constraints() if you want to read the pathLenConstraint field too.
A negative value may be returned in case of parsing error. If the certificate does not contain the basicConstraints extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
