curs_add_wchstr - Linux

Overview

The curs_add_wchstr command in Linux adds a wide-character string (including the terminating null character) to the current or specified window. It is primarily used for writing wide-character text to the terminal.

Syntax

curs_add_wchstr <-1|-2|n> <wchstr>

Options/Flags

  • -1: Add the string to the current window.
  • -2: Add the string to the previous window.
  • n: Add the string to the nth window. A value of 0 is taken to mean the current window. A negative value of n is equivalent to n being added to the total number of windows. The total number of windows can be determined with curs_get_winnum.
  • <wchstr>: The wide-character string to add to the window.

Examples

To add the wide-character string "Hello, world!" to the current window:

curs_add_wchstr -1 "Hello, world!"

To add the wide-character string "你好，世界！" to the previous window:

curs_add_wchstr -2 "你好，世界！"

Common Issues

One common issue is using non-wide character strings. The curs_add_wchstr command expects wide-character strings, so using non-wide character strings will result in unexpected behavior.

Integration

The curs_add_wchstr command can be combined with other Linux commands or tools for advanced tasks. For example, it can be used with the curs_addstr command to add both wide-character and non-wide character strings to a window.
