setlocale is a C standard-library function that selects or queries the program's current locale for locale-sensitive behavior.
- How it is used
- Selects the locale used for language-sensitive library behavior, especially before extended-character output or multibyte input.
- How deep it goes
- Defines the call and required locale choices, maps category scopes, and demonstrates placement before text processing; does not detail return-value handling.
- Examples
- Shows `setlocale(LC_ALL, "")` before extended-character output and `setlocale(LC_CTYPE, "")` before scanning multibyte input.
- What you can do after
- Operate/configure it to select the system-default locale for all categories or only character handling before locale-sensitive text processing.
