6.23.21 putwchar Function

Writes a wide character to stdout.

Include

<wchar.h>

Prototype

wint_t putwchar(wchar_t c);

Arguments

c

the wide character to write

Return Value

The function returns a copy of the wide character written. If a write or encoding error occurs, WEOF is returned.

Remarks

The function writes the wide character, c, to stdout and at the position indicated by the file position indicator for the stream (if defined), advancing the indicator appropriately. The error indicator for stdout will be set on a write error. If an encoding error occurs, errno is set to the value of the EILSEQ macro.

Example

#include <wchar.h>

int main(void)
{
  wint_t wc;

  for(wc = L'0'; iswdigit(wc); wc++)
    putwchar(wc);
  putwchar(L'\n');
}
