This macro declares three functions writing DVB strings using iconv.

You must add two members to your private pipe structure, for instance:

You must also declare UPIPE_HELPER_UPIPE prior to using this macro.

Supposing the name of your structure is upipe_foo, it declares:

• void upipe_foo_init_dvb_string(struct upipe *upipe)

  Initializes the fields.

• uint8_t *upipe_foo_alloc_dvb_string(struct upipe *upipe,
const char *string, const char *encoding, size_t *out_length_p)

  Allocates a buffer and stores a DVB string with the given encoding.

• void upipe_foo_clean_dvb_string(struct upipe *upipe)

  Releases the iconv handle.

Parameter list:

• STRUCTURE: name of your private upipe structure
• NATIVE_ENCODING: native encoding to convert to ("UTF-8")
• CURRENT_ENCODING: name of the const char * field of your private upipe structure
• ICONV_HANDLE: name of the iconv_t field of your private upipe structure
