keyFileErrorQuark :: (HasCallStack, MonadIO m) => m Word32 Source #

No description available in the introspection data.

getBoolean

keyFileGetBoolean Source #

Arguments

:: (HasCallStack, MonadIO m)
=> KeyFile	`keyFile`: a `KeyFile`
-> Text	`groupName`: a group name
-> Text	`key`: a key
-> m ()	(Can throw `GError`)

Returns the value associated with key under groupName as a boolean.

If key cannot be found then False is returned and error is set to G_KEY_FILE_ERROR_KEY_NOT_FOUND. Likewise, if the value associated with key cannot be interpreted as a boolean then False is returned and error is set to G_KEY_FILE_ERROR_INVALID_VALUE.

Since: 2.6
