[解决办法]
使用C语言调用系统shell批处理....
用批处理获取电脑机器码的方法
以下是获取cpu和硬盘序列号的组合ID
@echo off&setlocal ENABLEDELAYEDEXPANSION
set sig=0
for /f %%i in ('wmic DISKDRIVE get signature') do (
set /a sig+=1
if !sig!==2 set pcid=%%i
)
set sig=0
for /f %%i in ('wmic cpu get ProcessorId') do (
set /a sig+=1
if !sig!==2 set pcid=!pcid!%%i
)
echo cpu的id和硬盘序列号的组合为: %pcid%
pause
[解决办法]
cat /proc/version
cat /proc/cpuinfo
when /darwin9/
`hwprefs cpu_count`.to_i
when /darwin/
((`which hwprefs` != '') ? `hwprefs thread_count` : `sysctl -n hw.ncpu`).to_i
when /linux/
`cat /proc/cpuinfo
[解决办法]
grep processor
[解决办法]
wc -l`.to_i
when /freebsd/
`sysctl -n hw.ncpu`.to_i
when /mswin
