## Function Documentation

std::string CPPCMS_API cppcms::util::escape | ( | std::string const & | s | ) |

Escape string for inclusion in HTML page, i.e.

- < - &lt;
- > - &gt;
- & - &amp;
- " - &quot;
- &#39; - &#39;

Note, this function does not deal with encodings, so it's up to you to provide valid text encoding

void CPPCMS_API cppcms::util::escape | ( | char const * | begin,
|  | char const * | end,
|  | std::ostream & | output
| ) |  |

Escape string for inclusion in HTML page, i.e.

- < - &lt;

int CPPCMS_API cppcms::util::escape | ( | char const * | begin,
|  | char const * | end,
|  | std::streambuf & | output
| ) |  |

Escape string for inclusion in HTML page, i.e.
