CreateDirectory失败，权限被拒绝

Question

I am running one dll under window C# application. APP call dll api for all the transaction with the system. While I try for creating directory at C# app level it creates successfully but the calls fail with permission denied if dll calls createDirectory method. Process has full control permission.

................ code snippet ................

int dlnaFileSystemNewDirPeer(char *in_name)
{
    int len = dlna_strlen(in_name);
    wchar_t sbuff[100];
    swprintf(sbuff, len, L"%p", in_name);
    int ret = CreateDirectory(sbuff, NULL);
    int err = GetLastError();
    if (err) {
        printf("CreateDirectory fails with error:%d\n", err);
        return err;
    }
    return ret;
}

Answer 1

swprintf(sbuff, len, L"%p", in_name);

You try to create the directory 0x1324000 (or whatever the address of your in_name is).

Use %S (note the uppercase S ) or %ws , depending on the runtime you are linking against.

See this if you are using Visual studio.
