const char* stp_get_release_version | ( | void |  | ) |

Get the library release version string (x.y)

Returns:
  a pointer to the release name of the package, which must not be modified or freed.

const char* stp_get_version | ( | void |  | ) |

Get the library version string (x.y.z)

Returns:
  a pointer to the version name of the package, which must not be modified or freed.

int stp_init | ( | void |  | ) |

Initialise libgimpprint.

This function must be called prior to any other use of the library. It is responsible for loading modules and XML data and initialising internal data structures.

Returns:
  0 on success, 1 on failure.

|  | const char * | format,
|  |  | ...
| ) |  |

const char* stp_set_output_codeset | ( | const char * | codeset | ) |

Set the output encoding.

This function sets the encoding that all strings translated by gettext are output in. It is a wrapper around the gettext bind_textdomain_codeset() function.

Parameters:

  codeset | the standard name of the encoding, which must be usable with iconv_open(). For example, "US-ASCII" or "UTF-8". If NULL, the currently-selected codeset will be returned (or NULL if no codeset has been selected yet).

Returns:
  a string containing the selected codeset, or NULL on failure (errno is set accordingly).
