NAME¶
gnutls_x509_crt_get_basic_constraints - API function
SYNOPSIS¶
#include <gnutls/x509.h>
int gnutls_x509_crt_get_basic_constraints(gnutls_x509_crt_t
cert, unsigned int * critical, unsigned int *
ca, int * pathlen);
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
- 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.
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).
RETURNS¶
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.
