I think after call vlc_readdir(), it need to free return value. But this is not right way.
Please check about that.

Hi.

I'm sorry I misunderstand typecast part.

/src/win32/filesystem.c

***line 171

char *vlc_readdir (DIR *dir)
{
vlc_DIR *p_dir = (vlc_DIR *)dir; <----------- This parameter dir is to make with vlc_opendir(). dir value is same vlc_DIR *.


I'm very sorry.

If you have a time, please to check before free(p_dir->entry) and to set NULL.

like...

vlc_fs.h

static inline int vlc_closedir( DIR *dir )
{
vlc_DIR *vdir = (vlc_DIR *)dir;
_WDIR *wdir = vdir->wdir;

if (vdir->entry != NULL)
free( vdir->entry );


filesystem.c

char *vlc_readdir (DIR *dir)
{
vlc_DIR *p_dir = (vlc_DIR *)dir;

if (p_dir->entry != NULL)
{
free(p_dir->entry);
p_dir->entry = NULL;
}




Have a nice day~~~
