qconv_blinded_sig()

static int qconv_blinded_sig ( void *  cls, const void *  data, size_t  data_len, void *  param_values[], int  param_lengths[], int  param_formats[], unsigned int  param_length, void *  scratch[], unsigned int  scratch_length  )

static

Function called to convert input argument into SQL parameters.

Parameters

	cls	closure
	data	pointer to input argument
	data_len	number of bytes in data (if applicable)
[out]	param_values	SQL data to set
[out]	param_lengths	SQL length data to set
[out]	param_formats	SQL format data to set
	param_length	number of entries available in the param_values, param_lengths and param_formats arrays
[out]	scratch	buffer for dynamic allocations (to be done via GNUNET_malloc()
	scratch_length	number of entries left in scratch

Returns

-1 on error, number of offsets used in scratch otherwise
