19 Converts an ISO 639-2 language code to an RFC 4646 language code.
20 If the ISO 639-2 language code has a corresponding ISO 639-1 code, then that ISO 639-1
21 code is returned in the out parameter. Else the original ISO 639-2 code is returned. The returned RFC 4646
22 language code is composed of only a primary language subtag.
24 If Iso639Language is NULL, then ASSERT().
25 If Rfc4646Language is NULL, then ASSERT().
27 @param[out] Rfc4646Language Pointers to a buffer large enough for an ASCII string
28 representing an RFC 4646 language code containing only
29 either a ISO 639-1 or ISO 639-2 primary language subtag.
30 This string is Null-terminated.
31 @param[in] Iso639Language The pointer to a 3-letter ASCII string that represents
32 an ISO 639-2 language code. This string is not required
33 to be Null-terminated.
35 @retval TRUE The ISO 639-2 language code was converted to an ISO 639-1 code.
36 @retval FALSE The language code does not have a corresponding ISO 639-1 code.

47 Converts an RFC 4646 language code to an ISO 639-2 language code. The primary language
48 subtag of the RFC 4646 code must be either an ISO 639-1 or 639-2 code. If the primary
49 language subtag is an ISO 639-1 code, then it is converted to its corresponding ISO 639-2
50 code (T code if applies). Else the ISO 639-2 code is returned.
52 If Rfc4646Language is NULL, then ASSERT().
53 If Iso639Language is NULL, then ASSERT().

56 representing an ISO 639-2 language code. The string
58 @param[in] Rfc4646Language The pointer to a RFC 4646 language code string.
59 This string is terminated
60 by a NULL or a ';' character.
62 @retval TRUE Language code converted successfully.
63 @retval FALSE The RFC 4646 language code is invalid or unsupported.

74 Converts ISO 639-2 language codes to RFC 4646 codes and returns the converted codes.
75 Caller is responsible for freeing the allocated buffer.

79 @param[in] Iso639Languages Pointers to Null-terminated ISO 639-2 language code strings containing
80 one or more ISO 639-2 3-letter language codes.

83 @retval NULL Out of memory.
84 @return The pointer to the allocate buffer containing the
85 Null-terminated converted language codes string.
86 This string is composed of one or more RFC4646
87 language codes each of which has only
88 ISO 639-1 2-letter primary language subtag.

98 Converts RFC 4646 language codes to ISO 639-2 codes and returns the converted codes.

100 Caller is responsible for freeing the allocated buffer.
