NAME
       gnutls_x509_crt_export - API function

SYNOPSIS
       #include <gnutls/x509.h>

       int gnutls_x509_crt_export(gnutls_x509_crt_t cert,
       gnutls_x509_crt_fmt_t format, void * output_data, size_t *
       output_data_size);

ARGUMENTS
       gnutls_x509_crt_t cert
                   Holds the certificate

       gnutls_x509_crt_fmt_t format
                   the format of output params. One of PEM or DER.

       void * output_data
                   will contain a certificate PEM or DER encoded

       size_t * output_data_size
                   holds the size of output_data (and will be replaced by the
                   actual size of parameters)

DESCRIPTION
       This function will export the certificate to DER or PEM format.

       If the buffer provided is not long enough to hold the output, then
       *output_data_size is updated and GNUTLS_E_SHORT_MEMORY_BUFFER will be
       returned.

       If the structure is PEM encoded, it will have a header of "BEGIN
       CERTIFICATE".

RETURNS
       In case of failure a negative error code will be returned, and 0 on
       success.
