51 * @G_VARIANT_PARSE_ERROR_FAILED: generic error (unused)
52 * @G_VARIANT_PARSE_ERROR_BASIC_TYPE_EXPECTED: a non-basic #GVariantType was given where a basic type was expected
53 * @G_VARIANT_PARSE_ERROR_CANNOT_INFER_TYPE: cannot infer the #GVariantType
54 * @G_VARIANT_PARSE_ERROR_DEFINITE_TYPE_EXPECTED: an indefinite #GVariantType was given where a definite type was expected
55 * @G_VARIANT_PARSE_ERROR_INPUT_NOT_AT_END: extra data after parsing finished
56 * @G_VARIANT_PARSE_ERROR_INVALID_CHARACTER: invalid character in number or unicode escape
57 * @G_VARIANT_PARSE_ERROR_INVALID_FORMAT_STRING: not a valid #GVariant format string
58 * @G_VARIANT_PARSE_ERROR_INVALID_OBJECT_PATH: not a valid object path
59 * @G_VARIANT_PARSE_ERROR_INVALID_SIGNATURE: not a valid type signature
60 * @G_VARIANT_PARSE_ERROR_INVALID_TYPE_STRING: not a valid #GVariant type string
61 * @G_VARIANT_PARSE_ERROR_NO_COMMON_TYPE: could not find a common type for array entries
62 * @G_VARIANT_PARSE_ERROR_NUMBER_OUT_OF_RANGE: the numerical value is out of range of the given type

2310 * @Returns: a reference to a #GVariant, or %NULL
2312 * Parses a #GVariant from a text representation.
2314 * A single #GVariant is parsed from the content of @text.
2316 * The format is described <link linkend='gvariant-text'>here</link>.
2318 * The memory at @limit will never be accessed and the parser behaves as
2319 * if the character at @limit is the nul terminator. This has the
2320 * effect of bounding @text.
2322 * If @endptr is non-%NULL then @text is permitted to contain data
2323 * following the value that this function parses and @endptr will be
2324 * updated to point to the first character past the end of the text
2325 * parsed by this function. If @endptr is %NULL and there is extra data
2326 * then an error is returned.
2328 * If @type is non-%NULL then the value will be parsed to have that
2329 * type. This may result in additional parse errors (in the case that
2330 * the parsed value doesn't fit the type) but may also result in fewer
2331 * errors (in the case that the type would have been ambiguous, such as
2332 * with empty arrays).
2334 * In the event that the parsing is successful, the resulting #GVariant
2337 * In case of any error, %NULL will be returned. If @error is non-%NULL
2338 * then it will be set to reflect the error that occured.
2340 * Officially, the language understood by the parser is "any string
2341 * produced by g_variant_print()".
