Function Details : wcwidth

intwcwidth(wchar_t wc) ;

Return Type : int

Integer type (typically 4 bytes, -2,147,483,648 to 2,147,483,647)

Read about return values of wcwidth function .

1st Parameter Type : wchar_t

A data type used to represent wide characters, typically supporting larger character sets such as Unicode. Its size is platform-dependent but is often 2 or 4 bytes.

1st Parameter

The wide character whose display width is to be determined.

The wcwidthfunction in C language Determines the number of column positions required for a wide character.

wcwidth determines the number of column positions on a display device required for the wide character wc. The behavior of this function is affected by the LC_CTYPE category of the current locale.

The wcwidthfunction takes 1 parameter:

•
wchar_t `wc`: The wide character whose display width is to be determined.

Determines the number of column positions required to display the wide character `wc`. Returns the width in column positions (0 for non-spacing characters, 1 or more for spacing characters), or `-1` if the wide character is not printable.

The wcwidth function return value :

Returns the number of column positions occupied by wc, or -1 if wc is not printable
If wc is a null wide character, it returns 0

Output

This example demonstrates the basic usage of wcwidth to determine the display width of various characters, including ASCII, non-ASCII, and control characters.
