### Example (getwc -- Read Wide Character from Stream)

This example opens a file and uses getwc to read wide characters from the file.

    #include <stdio.h>
    #include <stdlib.h>
    #include <wchar.h>
    #include <errno.h>

    int main(void)
    {
       FILE   *stream;
       wint_t wc;

       if (NULL == (stream = fopen("fgetwc.dat", "r"))) {
          printf("Unable to open: \"fgetwc.dat\"\n");
          exit(1);
       }

       errno = 0;
       while (WEOF != (wc = fgetwc(stream)))
          printf("wc = %lc\n", wc);

       if (EILSEQ == errno) {
          printf("An invalid wide character was encountered.\n");
          exit(1);
       }
       fclose(stream);
       return 0;

       /********************************************************
          Assuming the file fgetwc.dat contains:

          Hello world!

          The output should be similar to:

          wc = H
          wc = e
          wc = l
          wc = l
          wc = o
          :
       ********************************************************/
