gnutls_x509_crt_get_ca_status - Man Page

#include <gnutls/x509.h>

int gnutls_x509_crt_get_ca_status(gnutls_x509_crt_t cert, unsigned int * critical);

gnutls_x509_crt_t cert

should contain a gnutls_x509_crt_t type

unsigned int * critical

will be non-zero if the extension is marked as critical

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 (0) 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.

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.
