NAME
       gnutls_x509_crq_get_basic_constraints - API function

SYNOPSIS
       #include <gnutls/x509.h>

       int gnutls_x509_crq_get_basic_constraints(gnutls_x509_crq_t crq, unsigned int * critical, unsigned int * ca, int * pathlen);

ARGUMENTS
       gnutls_x509_crq_t crq
		   should contain a gnutls_x509_crq_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_AVAIL-
       ABLE will be returned.
