       char *strrtrim(char *s);

       string.  As whitespace is counted everything for which isspace(3)
       returns true.

EXAMPLE
       To remove whitespace from the end of all lines, you might do the
       following:

            #include <publib.h>

            int main(void) {
                 char line[512];

                 while (fgets(line, sizeof(line), stdio) != NULL) {
                      strrtrim(line);
                      printf("%s", line);
                 }
                 return 0;
            }
