strstr的使用？？？

[quote]原帖由 "yujf"]有一字符串“sthx=xxx|sthss=xyx|sthyy=xyyy”,怎么样才可以通过“sthx”来得到他的值“xxx”，写一函数来实现？[/quote 发表：

如果是这个固定的格式，那可以用下标来取,比如：

1. 
   
2. char buf[100] = "sthx=xxx|sthss=xyx|sthyy=xyyy";
   
3. char a = buf[5];
   
4. char b = buf[6];
   
5. char c = buf[7];
   

复制代码

这样不就可以得到XXX了吗，如果XXX是个int那就转换一下了。
这是我的一点建议，不知道楼主是不是这个意思。

Function: char * strstr (const char *haystack, const char *needle)
This is like strchr, except that it searches haystack for a substring needle rather than just a single character. It returns a pointer into the string haystack that is the first character of the substring, or a null pointer if no match was found. If needle is an empty string, the function returns haystack.

For example,

strstr ("hello, world", "l"
    =>; "llo, world"
strstr ("hello, world", "wo"
    =>; "world"
