Re: [問題] 在不同process間使用callback function
※ 引述《chengcti (卡馬請出來面對!!)》之銘言：
: 1. IPC / mailslot, pipe, message.
: not easy
: 2. file share (a simple method)
: A, B always check a file every n secs.
: When C writes a flag to file.
: The A & B read it, and call his function.
I recommand the original author to use dll
shared memory.
It doesn't get the drawback of frequently file I/O
as you described above.
Shared memory can be mapped to a different address in
each process. For this reason, each process has its own
instance of memory pointer, which is declared as a global
variable so that it is available to all DLL functions.
You can integrate the memory content and callback funcitons
together, to achieve your purpose.
