我ctypes在Python中使用它来打开一个用C++编写的文件.

我的C++代码:

extern "C" {
void openfile(const char *filename) {
    cout<<"File to open for writing = " <<filename<<endl;
    FILE *fp = fopen(filename,"w");
    fprintf(fp,"writing into file");
    fclose(fp);
}
}

我的Python代码:

>>> import ctypes
>>> lib = ctypes.cdll.LoadLibrary('/in/vrtime/mahesh/blue/rnd/software/test/test.so')
>>> outfile = "myfirstfile.txt"
>>> lib.openfile(outfile)
File to open for writing = m

我得到的文件名是m,这是char我文件的第一个字符.

如何将整个字符串传递给C端？
