# [NAME](#NAME)

unibi\_get\_ext\_bool, unibi\_set\_ext\_bool, unibi\_get\_ext\_num, unibi\_set\_ext\_num, unibi\_get\_ext\_str, unibi\_set\_ext\_str - access the extended capabilities of a terminal object

# [SYNOPSIS](#SYNOPSIS)

```
 #include <unibilium.h>
 int unibi_get_ext_bool(const unibi_term *ut, size_t i);
 int unibi_get_ext_num(const unibi_term *ut, size_t i);
 const char *unibi_get_ext_str(const unibi_term *ut, size_t i);
 
 void unibi_set_ext_bool(unibi_term *ut, size_t i, int b);
 void unibi_set_ext_num(unibi_term *ut, size_t i, int v);
 void unibi_set_ext_str(unibi_term *ut, size_t i, const char *s);
```

# [DESCRIPTION](#DESCRIPTION)

Get/set extended boolean, numeric, and string capabilities. *i* is the index of the extended capability to act on; it must be less than unibi\_count\_ext\_bool(ut), unibi\_count\_ext\_num(ut), or unibi\_count\_ext\_str(ut), respectively.

Note that "unibi\_set\_ext\_str" simply stores the pointer it is given; it will not free *s* or make a copy of the string.
