int TCT_Local_Control_Interrupts(int mask): sets the interrupt mask. Returns the previous mask.
int NU_Current_Dir(const char *drive, char *path): fills in path with the full path name of the current working directory. Returns 0 on success. If drive is null or an invalid drive specifier the default drive is used.
int NU_Get_First(struct dstat *statobj, const char * pattern): given a pattern which contains both a path specifier and a search pattern, fills in the structure at statobj with information about the file and sets up internal parts of statobj to supply appropriate information for calls to NU_Get_Next. Returns 0 if a match was not found.
int NU_Get_Next(struct dstat *statobj): given a pointer to a DSTAT structure that has been set up by a call to NU_Get_First(), searches for the next match of the original pattern in the original path. Returns 0 if found and updates statobj for subsequent calls to NU_Get_Next.
void NU_Done(struct dstat *statobj): given a pointer to a DSTAT structure that has been set up by a call to NU_Get_First(), frees internal elements used by the statobj.
NU_Set_Current_Dir(const char *name): Set the current working directory on the default drive.

void ascii2utf16(void *buf, const char *str, int max_size): converts the ASCII string str to the UTF-8 string buf of size max_size.
void show_dialog_box2(int winid, const char *utf8_title, const char *utf8_msg): displays a dialog box of title utf8_title containing utf8_msg. utf8_title and utf8_msg are C strings converted with ascii2utf16(). winid must be 0 (deprecated since Ndless 2.0 and replaced with libndls's show_msgbox).
