|
|
|
* В исходный код calcreadconfig.c внесены следующие изменения:
|
|
|
* - если параметр .conf или .cfg, то это конфигурационный файл меню
|
|
|
* в остальных случаях параметры аккумулируются в дополнения для передачи
|
|
|
* далее
|
|
|
* - если параметре, значения которого перечислены через запятую возможна
|
|
|
* замена одного из значений (например переходящий параметр test=1,2,3
|
|
|
* test=,,6 заменит в этом параметре последнее занчение => test=1,2,6
|
|
|
* - добавлены функции разбивки и объединения строки
