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 (


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.
