我编写了一个程序来读取测试文件并在C程序中填充结构值。
所有其他事情都没问题。
但是，当我尝试填充界面值结构时，它会显示最近的strtok()值。
测试文件看起来像，
[text file] TYPE VM vm1 TYPE PM pm1 NODES 2 APS 2 TYPE wired NODE-1 NUM_IF 2 NODE-1 IP_ADDR_ETH-0 10.114.12.1 NODE-1 IP_ADDR_ETH-1 10.114.12.2 NODE-1 VM_ID 1 NODE-1 MEM_SIZE 512 NODE-1 OS FEDORA NODE-2 NUM_IF 3 NODE-2 IP_ADDR_ETH-0 10.114.14.1 NODE-2 IP_ADDR_ETH-1 10.114.14.2 NODE-2 IP_ADDR_ETH-2 10.114.14.3 NODE-2 VM_ID 2 NODE-2 MEM_SIZE 1GB NODE-2 OS CENTOS NODE-2 10.114.12.7 [/textfile]

我的问题是什么？
答案 0 :(得分：0)
commontoolinfo.num_nodes=a;
use strcpy(commontoolinfo.num_nodes,a)
...因为strtok会返回char * value ...
