Function

Jsongvariant_deserialize

Declaration [src]

GVariant*
json_gvariant_deserialize (
  JsonNode* json_node,
  const gchar* signature,
  GError** error
)

Description [src]

Converts a JSON data structure to a GVariant.

If signature is not NULL, it will be used to resolve ambiguous data types.

If no error occurs, the resulting GVariant is guaranteed to conform to signature.

If signature is not NULL but does not represent a valid GVariant type string, NULL is returned and the error is set to G_IO_ERROR_INVALID_ARGUMENT.

If a signature is provided but the JSON structure cannot be mapped to it, NULL is returned and the error is set to G_IO_ERROR_INVALID_DATA.

If signature is NULL, the conversion is done based strictly on the types in the JSON nodes.

The returned variant has a floating reference that will need to be sunk by the caller code.
