Function Details : putwchar

wint_tputwchar(wchar_t wc) ;

Return Type : wint_t

An integer type capable of storing any wide character value or the special value WEOF, used in wide-character input/output functions.
Read about return values of putwchar 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 to be written to the standard output (`stdout`).

The putwcharfunction in C language Writes a wide character to the standard output stream.
The putwchar function writes a single wide character to the standard output stream (stdout). It's equivalent to putwc(wc, stdout). This function is particularly useful for outputting non-ASCII characters to the console in a locale-aware manner.
The putwcharfunction takes 1 parameter:
  • •
    wchar_t `wc`: The wide character to be written to the standard output (`stdout`).
Writes the wide character `wc` to the standard output (`stdout`). Returns the character written as a `wint_t` on success or `WEOF` if an error occurs. The function is commonly used for wide-character output in locales supporting extended character sets.
The putwchar function return value :
  • Returns the wide character written as a wint_t value if successful, or WEOF if an error occurred

Output

This example demonstrates writing a wide character (an emoji) to stdout using putwchar. It includes proper locale setting and error checking.
