strrtrim  removes  all trailing whitespace characters from the end of a string.  As whitespace is counted
       everything for which isspace(3) returns true.

       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;
            }
