lwIP 文件名中的 arch 是什么意思?

What does arch mean in lwIP file names?

archlwIP个文件名中是什么意思?我试着猜测和思考 "archive" 或 "archaic" 但它们似乎不同。

lwIP 中的

arch 来自 架构 。如 documentation of sys_arch.txt in GitHub 中所写:

The operating system emulation layer is located in two files, cc.h and sys_arch.c. The operating system emulation layer provides a common interface between the lwIP code and the underlying operating system kernel. The general idea is that porting lwIP to new architectures requires only small changes to a few header files and a new sys_arch implementation.
