## NAME

unibi\_del\_ext\_bool, unibi\_del\_ext\_num, unibi\_del\_ext\_str - remove extended capabilities from a terminal object

## SYNOPSIS

```
 #include <unibilium.h>
 void unibi_del_ext_bool(unibi_term *ut, size_t i);
 void unibi_del_ext_num(unibi_term *ut, size_t i);
 void unibi_del_ext_str(unibi_term *ut, size_t i);
```

## DESCRIPTION
