Synopsis:
    #include <stdio.h>
    int putchar( int c );
    #include <wchar.h>
    wint_t putwchar( wint_t c );

Description:
    The putchar function writes the character specified by the argument c to
    the output stream  stdout.

    The function is equivalent to


         fputc( c, stdout );

    The putwchar function is identical to putchar except that it converts
    the wide character specified by c to a multibyte character and writes it
    to the output stream.

Returns:
    The putchar function returns the character written or, if a write error
    occurs, the error indicator is set and putchar returns  EOF.

    The putwchar function returns the wide character written or, if a write
    error occurs, the error indicator is set and putchar returns  WEOF.

    When an error has occurred,  errno contains a value indicating the type
    of error that has been detected.

Example:
    #include <stdio.h>

    void main()
      {
        FILE *fp;
        int c;

        fp = fopen( "file", "r" );
        c = fgetc( fp );
        while( c != EOF ) {
            putchar( c );
            c = fgetc( fp );
        }
        fclose( fp );
      }

    putchar is ANSI, putwchar is ANSI
