Function Documentation

value_to_string()

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

static

Convert the 'value' of a record to a string.

Parameters

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

Returns

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

string_to_value()

static int string_to_value ( void *  cls, uint32_t  type, const char *  s, void **  data, size_t *  data_size  )

static

Convert human-readable version of a 'value' of a record to the binary representation.

Parameters

cls	closure, unused
type	type of the record
s	human-readable string
data	set to value in binary encoding (will be allocated)
data_size	set to number of bytes in data

Returns
