    Command:

    gnutls_x509_crt_get_basic_constraints

    
    
    

    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 oth-
                       erwise.
    
           int * pathlen
                       pointer to output integer indicating path  length  (may  be
                       NULL), non-negative error codes indicate a present pathLen-
                       Constraint 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 exten-
           sion (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.
