How to get infomations of Unix system?

I want APIs for getting informations of system (for general version). Such as the CPU type, number of memory, harddisk type, moniter type, CDROM type, even mouse type and keyboard type.

there is no general API for UNIX, 'cause this depends on hardware and OS. You need to use the machines proprietary libs, i.e. /proc filesystem on Linux and FreeBSD, or statvfs(), sysfs(), sysconf() on Solaris, etc. etc.
