Methods

bytesNeeded

dBusMessageBytesNeeded Source #

Arguments

:: (HasCallStack, MonadIO m)
=> ByteString	`blob`: A blob representing a binary D-Bus message.
-> m Int64	Returns: Number of bytes needed or -1 if `error` is set (e.g. if `blob` contains invalid data or not enough data is available to determine the size). (Can throw `GError`)

Utility function to calculate how many bytes are needed to completely deserialize the D-Bus message stored at blob.
