我写了一个程序来读取测试文件并在C程序中填充结构值。为结构数组问题分配值？
其他所有的东西都可以。
但是，当我尝试填充界面值结构时，它显示最近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]

什么是我的问题吗？
请通过最小化源代码，这是需要重现该问题的测试数据减少的问题。这样，人们不必浪费时间（和脑细胞）理解不相关的代码。 – 2011-03-28 13:43:47
