Declaration [src]

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.

Type: JsonNode

The node to convert.

The data is owned by the caller of the function.

Type: const gchar*

A valid GVariant type string.

The argument can be NULL.
The data is owned by the caller of the function.
The value is a NUL terminated UTF-8 string.

Type: GError **

The return location for a recoverable error.

The argument can be NULL.
If the return location is not NULL, then you must initialize it to a NULL GError*.
The argument will be left initialized to NULL by the function if there are no errors.
In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: GVariant

A newly created GVariant.

The data is owned by the called function.
The return value can be NULL.
