basic_value_to_string()

static char * basic_value_to_string ( void *  cls, uint32_t  type, const void *  data, size_t  data_size  )

static

Convert the 'value' of an attribute to a string.

Parameters

cls	closure, unused
type	type of the attribute
data	value in binary encoding
data_size	number of bytes in data

Returns

NULL on error, otherwise human-readable representation of the value
