查找子字符串的函数？

[lebron]

没有装帮助很麻烦，想在str字符串中查找是否存在子字符串“test"，有没有这样的函数呢？

[zjx95]

c的strstr
CString的Find等等

[折腾_苏州]

strstr(str,"test") //在串中查找指定字符串的第一次出现

CString str; str.Find("test") //
Return Value
The zero-based index of the first character in this CString object that matches the requested substring or characters; -1 if the substring or character is not found.
