parse
Description:
Parses a Variant from a text representation.
A single Variant is parsed from the content of text
.
The format is described [here](gvariant-text-format.html).
The memory at limit
will never be accessed and the parser behaves as if the character at limit
is the nul terminator.
This has the effect of bounding text
.
If endptr
is non-null then text
is permitted to contain data following the value
that this function parses and endptr
will be updated to point to the first character past the end of the text parsed by this
function. If endptr
is null and there is extra data then an error is returned.
If type
is non-null then the value will be parsed to have that type. This may result in
additional parse errors (in the case that the parsed value doesn't fit the type) but may also result in fewer errors (in the case that the type
would have been ambiguous, such as with empty arrays).
In the event that the parsing is successful, the resulting Variant is returned. It is never floating, and must be freed with [method@GLib.Variant.unref].
In case of any error, null will be returned. If throws is non- null then it will be set to reflect the error that occurred.
Officially, the language understood by the parser is “any string produced by [method@GLib.Variant.print]”. This explicitly includes `g_variant_print()`’s annotated types like `int64 -1000`.
There may be implementation specific restrictions on deeply nested values, which would result in a g_variant_parse_error_recursion error. Variant is guaranteed to handle nesting up to at least 64 levels.
Parameters:
type |
a VariantType, or null |
text |
a string containing a GVariant in text form |
limit |
a pointer to the end of |
endptr |
a location to store the end pointer, or null |
Returns:
a non-floating reference to a Variant, or null |
