| - | A more complex example can be found in [[configparser]] in function readFile(). The function resembles a state machine with 5 states (see enum SPLIT_LINE_STATE). It is possible to provide the starting state of the machine which gives you the ability to resume tokenization of a string in some cases. In resuming mode (start_state != SL_NORMAL) the read in characters are appended to the last string in the string vector //ret// until the state switches back to SL_NORMAL. In [[configparser]] this behaviour was used to read in multiline values. However this features does not give you the ability to split a string anywhere yourself and then pass it over to split_line (using the return state as new start_state). The outcome will be different from what you might expect in most cases! | + | A more complex example can be found in [[cfg_parser]] in function readFile().
