LP的含义是长指针(long pointer)。LPSTR是一个指向以‘\0’结尾的ANSI字符数组的指针,与char*可以互换使用,在win32中较多地使用LPSTR。而LPCSTR中增加的‘C’的含义是“CONSTANT”(常量),表明这种数据类型的实例不能被使用它的API函数改变,除此之外,它与LPSTR是等同的。
LPCWSTR是一个Windows API中的数据类型,表示指向以null结尾的Unicode字符数组的指针。它是长指针常量(Long Pointer to Constant Wide String)...
LPCWSTR 来自 英文 "Long Pointer to Constant Wide String" 的缩写。MS VC++ 里 用来指向 2字节 那种宽字符的 字符串。例如，中文汉字常用2字节编码。赋值问题，类似 给字符串赋初值那样，关键是要 明确告诉 本字符串是 宽字符串。用 L"字符串" 就可以实现了。例如：LPCWSTR a = L"Test...
