复制文件到 windir c

Question

我需要复制一个文件到windir，所以我这样做：

TCHAR windir[MAX_PATH];
GetWindowsDirectory(windir, MAX_PATH);

获取windir。

char newLocation[]="text.txt"; // how to add the windir here?
BOOL stats=0;
CopyFile(filename, newLocation, stats);

我的问题是，我想在 char newLocation[] 中的 text.txt 之前添加 windir 值。

有什么想法吗？

你试过像这样连接字符串吗？

#include <stdlib.h>
#include <string.h>

char* concat(char *s1, char *s2)
{
    char *result = malloc(strlen(s1)+strlen(s2)+1);//+1 for the zero-terminator
    //in real code you would check for errors in malloc here
    strcpy(result, s1);
    strcat(result, s2);
    return result;
}

如果不行，请 wcscat() 试一试！
