GioActionparse_detailed_name

Declaration [src]
gboolean
g_action_parse_detailed_name (
const gchar* detailed_name,
gchar** action_name,
GVariant** target_value,
GError** error
)
Description [src]
Parses a detailed action name into its separate name and target components.
Detailed action names can have three formats.
The first format is used to represent an action name with no target
value and consists of just an action name containing no whitespace
nor the characters :, ( or ). For example: app.action.
The second format is used to represent an action with a target value
that is a non-empty string consisting only of alphanumerics, plus -
and .. In that case, the action name and target value are
separated by a double colon (::). For example:
app.action::target.
The third format is used to represent an action with any type of
target value, including strings. The target value follows the action
name, surrounded in parens. For example: app.action(42). The
target value is parsed using g_variant_parse(). If a tuple-typed
value is desired, it must be specified in the same way, resulting in
two sets of parens, for example: app.action((1,2,3)). A string
target can be specified this way as well: app.action('target').
For strings, this third format must be used if target value is
empty or contains characters other than alphanumerics, - and ..
If this function returns TRUE, a non-NULL value is guaranteed to be returned
in action_name (if a pointer is passed in). A NULL value may still be
returned in target_value, as the detailed_name may not contain a target.
If returned, the GVariant in target_value is guaranteed to not be floating.

Parameters
detailed_name-
Type:
const gchar*A detailed action name.
The data is owned by the caller of the function. The value is a NUL terminated UTF-8 string. action_name-
Type:
gchar**The action name.
The argument will be set by the function. The argument can be NULL.The caller of the function takes ownership of the returned data, and is responsible for freeing it. The value is a NUL terminated UTF-8 string. target_value-
Type:
GVariantThe target value, or
NULLfor no target.The argument will be set by the function. The argument can be set to NULLby the function.The argument can be NULL.The caller of the function takes ownership of the returned data, and is responsible for freeing it. 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 aNULLGError*.The argument will be left initialized to NULLby 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.
