## Return Value

Each of these functions returns a nonnegative value if it is successful. On an error, **fputs** and **fputws** return **EOF**. If *str* or *stream* is a null pointer, these functions invoke the invalid parameter handler, as described in [Parameter Validation](../../c-runtime-library/parameter-validation.md). If execution is allowed to continue, these functions set **errno** to **EINVAL** and then **fputs** returns **EOF**, and **fputws** returns **WEOF**.

See [_doserrno, errno, _sys_errlist, and _sys_nerr](../../c-runtime-library/errno-doserrno-sys-errlist-and-sys-nerr.md) for more information on these, and other, error codes.
