Method

JsonParserload_from_mapped_file

since: 1.6

Declaration [src]

gboolean
json_parser_load_from_mapped_file (
  JsonParser* parser,
  const gchar* filename,
  GError** error
)

Description [src]

Loads a JSON stream from the content of filename and parses it.

Unlike json_parser_load_from_file(), filename will be memory mapped as read-only and parsed. filename will be unmapped before this function returns.

If mapping or reading the file fails, a G_FILE_ERROR will be returned.

Available since: 1.6

Parameters

filename

Type: const gchar*

The path for the file to parse.

The data is owned by the caller of the method.

The value is a file system path, using the OS encoding.

error

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 method 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: gboolean

TRUE if the file was successfully loaded and parsed.
