i am trying to figure out how to use named pipes so that i can build an interface/api for the mt4 terminal..
i used the following code to create the pipe.
i found a program that i downloaded that is called pipelist.exe that shows a dump of all "named pipes" on my system.
it gives to me the dump listing below... what the heck are these other existing pipes on my windows 10 computer?
i used the following code to create the pipe.
