NAME        top

       gnutls_x509_crt_verify - API function

SYNOPSIS        top

#include <gnutls/x509.h>int gnutls_x509_crt_verify(gnutls_x509_crt_tcert, constgnutls_x509_crt_t *CA_list, unsignedCA_list_length, unsigned intflags, unsigned int *verify);

ARGUMENTS        top

       gnutls_x509_crt_t cert                   is the certificate to be verified       const gnutls_x509_crt_t * CA_list                   is one certificate that is considered to be trusted                   one       unsigned CA_list_length                   holds the number of CA certificate in CA_list       unsigned int flags                   Flags that may be used to change the verification                   algorithm. Use OR of the                   gnutls_certificate_verify_flags enumerations.       unsigned int * verify                   will hold the certificate verification output.

DESCRIPTION        top

       This function will try to verify the given certificate and return       its status. Note that a verification error does not imply a       negative return status. In that case theverify status is set.       The details of the verification are the same as ingnutls_x509_trust_list_verify_crt2().

RETURNS        top

       On success,GNUTLS_E_SUCCESS(0) is returned, otherwise a negative       error value.
