/**
* gnutls_ocsp_resp_print:
* @resp: The structure to be printed
* @format: Indicate the format to use
* @out: Newly allocated datum with (0) terminated string.
*
* This function will pretty print a OCSP response, suitable for
* display to a human.
*
* If the format is %GNUTLS_OCSP_PRINT_FULL then all fields of the
* response will be output, on multiple lines.
*
* The output @out->data needs to be deallocate using gnutls_free().
*
* Returns: On success, %GNUTLS_E_SUCCESS (0) is returned, otherwise a
* negative error value.
