linux下编程获取网卡的PCI插槽的总线号、设备号、功能号，请问哪位大神能告诉怎么实现吗，因项目要求需要获取这些信息（不用lspci命令）

[machelcheng]

自己网上找了好久，没找到有什么好方法，不能用lspci命令然后过滤数据，需要编程实现，有没大神能帮忙解答一下？急！感激不尽

that's easy. If you don't want to take advantage of lspci. get its source and see how it implements things... https://github.com/gittup/pciutils

oops, u can tell it simply parses some system files as well. So the parsing process seems inevitable In runs on the following systems: Linux (via /sys/bus/pci, /proc/bus/pci or i386 ports) FreeBSD (via /dev/pci) NetBSD (via libpci) OpenBSD (via /dev/pci) GNU/kFreeBSD (via /dev/pci) Solaris/i386 (direct port access) Aix (via /dev/pci and odmget) GNU Hurd (direct port access) Windows (direct port access) CYGWIN (direct port access)
