Implementation some functions before two different apps in C++

Description

Hello, I have an application written in C++ called "VanitySearch" (you can check on GitHub). I have a private modified version with additional features of another application called "BitCrack" (also on GitHub). I talk about this three functions: --continue (what allow me to specify my own key space for searching) --share x/y (what allow me dividing them into parts X by Y --continue (what allow me to save progress already scanned ranges (eg. always after 1 hour). The original version of VanitySearch has not have this features, but i cannot use BitCrack because other important functions was not have by BitCrack , where VanitySearch have already ...) In final anazyze - i choose better option to implement from BitCrack to VanitySearch because is faster and have many functions already implemented than the second app. I have half-quality coded vesion with this function , but coded on 1.15 version , where is 50% slower than new 1.17 released version. Unfortunately - i cannot implement the codes in new release to work correctly (50% faster and with have three options from BitCrack) To sum up - my final goal is VanitySearch 1.17 with GitHub, which also allows you to set --keyspace, --share, and --continue - these three options that BitCrack has, and I can give you files to view this old version if you want to something will be needed.) Regards Sorry for unclearly description... Translator + smartphone = that what you see ?
