Vc中获取传入参数

void splitpathex(const char *path,char *dir,char *filename)
{
    char * lastSlash;
    char    tmpChar;  

   lastSlash = const_cast<char*>(strrchr(path,'\\')); 
    
    tmpChar = *lastSlash;
    *lastSlash = '\0';
    
    if (dir)
        strcpy(dir,path);
    if (filename)
        strcpy(filename,lastSlash+1);
    
    *lastSlash = tmpChar;
}
