HP和RedHat上可以使用uuidgen来生成,solaris上命令:makeuuid

如何通过C++编程取得UUID?

1.安装libuuid库, libuuid.so.1包涵在e2fsprogs里,本人的系统为RedHat7.3,下载ftp://194.199.20.114/linux/redhat/7.3/en/os/i386/RedHat/RPMS/e2fsprogs-1.27-3.i386.rpm

2. 编辑文件uuid.cpp

#include <iostream>;

#include <stdio.h>;

#include <uuid/uuid.h>;

int main()

{

uuid_t uu;

uuid_generate( uu );

std::cout << uu << std::endl;

int i;

for(i=0;i<16;i++)

{

printf("%x ",uu);

}

printf("n");

return 0;

}

#g++ -c –g uuid.o uuid.cpp

#g++ -o –luuid uuid uuid.o

其中/usr/include/uuid/uuid.h中有uuid_t的定义:

typedef unsigned char uuid_t[16];
