## Detailed Description

Thin iconv() wrapper.

glibmm provides Glib::convert() and Glib::locale_to_utf8() which are likely more convenient than the raw iconv wrappers. However, creating an IConv object once and using the convert() method could be useful when converting multiple times between the same charsets.

## Constructor & Destructor Documentation

Glib::IConv::IConv | ( | const std::string & | to_codeset,
|  | const std::string & | from_codeset
| ) |  |

Open new conversion descriptor.

Parameters

  to_codeset | Destination codeset.
  from_codeset | Source codeset.

Exceptions

  Glib::ConvertError |

Glib::IConv::IConv | ( | GIConv | gobject | ) |
| explicit

Glib::IConv::~IConv | ( |  | ) |

Close conversion descriptor.

## Member Function Documentation

std::string Glib::IConv::convert | ( | const std::string & | str | ) |

Convert from one encoding to another.

Parameters

  str | The string to convert.

Returns
  The converted string.

Exceptions

  Glib::ConvertError |

GIConv Glib::IConv::gobj | ( |  | ) |
| inline

std::size_t Glib::IConv::iconv | ( | char ** | inbuf,
|  | gsize * | inbytes_left,
|  | char ** | outbuf,
|  | gsize * | outbytes_left
| ) |  |

Same as the standard UNIX routine iconv(), but may be implemented via libiconv on UNIX flavors that lack a native implementation.

glibmm provides Glib::convert() and Glib::locale_to_utf8() which are likely more convenient than the raw iconv wrappers.

Parameters

  inbuf | Bytes to convert.
  inbytes_left | In/out parameter, bytes remaining to convert in inbuf.
  outbuf | Converted output bytes.
  outbytes_left | In/out parameter, bytes available to fill in outbuf.

Returns
  Count of non-reversible conversions, or `static_cast<std::size_t>(-1)` on error.

void Glib::IConv::reset | ( |  | ) |

Reset conversion descriptor to initial state.

Same as `iconv(0, 0, 0, 0)`, but implemented slightly differently in order to work on Sun Solaris <= 7. It's also more obvious so you're encouraged to use it.
