REGINA_API bool regina::base64Decode | ( | const char * | in, |
size_t | inlen, | ||
char * | out, | ||
size_t * | outlen | ||
) |
Decodes the given sequence of base64 characters, and writes the resulting raw bytes into a preallocated output buffer.
The given base64 sequence should not contain any unexpected characters; even whitespace will cause the decoding procedure to abort.
The length of the output buffer is passed as the argument outlen. If an unexpected or invalid character is found, or the output buffer is exhausted, this routine will write as many output bytes as it can and then return false
. Otherwise (on success) it will return true
. Either way, it will reset outlen to the total number of bytes that were written.
The total number of output bytes is important to know, since the output array is not terminated in any special way.
in | the input sequence of base64 characters; this does not need to be terminated in any special way. |
inlen | the length of the input sequence. |
out | the output buffer into which the resulting raw bytes will be written. |
outlen | must contain the length of the output buffer on entry, and on exit contains the number of output bytes that were successfully written. |
true
if decoding was successful, or false
if the output buffer was exhausted or an unexpected input character was found.REGINA_API bool regina::base64Decode | ( | const char * | in, |
size_t | inlen, | ||
char ** | out, | ||
size_t * | outlen | ||
) |
Decodes the given sequence of base64 characters, and passes back a newly allocated array containing the results.
The out pointer will be set to this new array, and outlen will be set to the number of raw bytes in this output array. This array will be allocated using new
[], and the caller is responsible for destroying it using delete
[].
The given base64 sequence should not contain any unexpected characters; even whitespace will cause the decoding procedure to abort.
The length of the output buffer is passed as the argument outlen. If an unexpected or invalid character is found or the output buffer is exhausted, this routine will return false
, set out to null
, and leave outlen undefined. Otherwise (on success) it will return true
and set outlen to the total number of output bytes.
If the user is not interested in the length of the output array, a null pointer may be passed in the outlen argument. Note however that the output array is not terminated in any special way.
in | the input sequence of base64 characters; this does not need to be terminated in any special way. |
inlen | the length of the input sequence. |
out | the address of a pointer which will be set to the output array of raw bytes (or which will be set to null on failure). |
outlen | the address of an integer which will be set to the length of the output array (or which will be left undefined on failure). |
true
if decoding was successful, or false
if an unexpected input character was found or some other error occurred.REGINA_API void regina::base64Encode | ( | const char * | in, |
size_t | inlen, | ||
char * | out, | ||
size_t | outlen | ||
) |
Encodes the given sequence of raw bytes in base64, and writes the results into a preallocated output buffer.
The length of the output buffer is passed as the argument outlen. If the number of base64 characters required is less than outlen, a terminating null
will be written to the end of the output sequence. If the number of base64 characters is outlen or greater, this routine will output as many base64 characters as possible, up to a maximum of outlen.
The routine base64Length() can be used to precalculate precisely how many output characters will be required.
in | the sequence of input bytes; this does not need to be terminated in any special way. |
inlen | the length of the input sequence. |
out | the output buffer into which the resulting base64 characters will be written. |
outlen | the length of the output buffer. |
REGINA_API size_t regina::base64Encode | ( | const char * | in, |
size_t | inlen, | ||
char ** | out | ||
) |
Encodes the given sequence of raw bytes in base64, and passes back a newly allocated array containing the results.
The out pointer will be set to this new array, which will be null-terminated. This array will be allocated using new
[], and the caller is responsible for destroying it using delete
[].
If the output array is too large (in particular, the expected size will overflow a size_t
), the out pointer will be set to null
.
in | the sequence of input bytes; this does not need to be terminated in any special way. |
inlen | the length of the input sequence. |
out | the address of a pointer which will be set to the output array of base64 characters. |

REGINA_API char* regina::duplicate | ( | const std::string & | str | ) |
Creates a new C string that is a duplicate of the given C++ string.
The deallocation of the new C string is the responsibility of the caller of this routine.
str | the C++ string to duplicate. |
|
inline |
Creates a new IConvStream; see the class notes for details.
If the given encodings are invalid, this stream will still forward data to the given output stream but no conversion will take place.
See the iconv documentation for information on what encodings are supported. For the GNU C library implementation, valid encodings can be found by running iconv –list
.
dest | the destination output stream. |
srcCode | the character encoding for data that is to be written into this IConvStream. |
destCode | the character encoding for the translated data that will subsequently be written to the destination output stream. |
|
inline |
Creates a new stream buffer.
|
inline |
Determines whether the given character is a base64 printable character as used by the base64 routines in Regina.
The base64 printable characters are the letters (both upper-case and lower-case), digits, plus (+), and forward slash (/).
Note that the equals sign (=) is padding, and is not considered by this routine to be a base64 printable character.
ch | any character. |
true
if the given character is one of the base64 printable characters used in Regina, or false
if it is not.
|
inline |
Returns the iterator following the given iterator.
This function avoids having to explicitly create a temporary to increment.
Only the increment operator ++it
needs to be defined.
it | the iterator to examine. |

If this stream buffer is already open, it will be closed and then reopened with the given parameters.
Any data that is sent to this stream buffer will be translated from srcCode to destCode and passed on to the given output stream.
If the given encodings are invalid, this stream will still forward data to the given output stream but no conversion will take place.
See the iconv documentation for information on what encodings are supported. For the GNU C library implementation, valid encodings can be found by running iconv –list
.

mask | the bitmask to write. |
int_type regina::i18n::IConvStreamBuffer::overflow | ( | int_type | c | ) |
Sends buffered data to the destination output stream, converting between character sets en route.
The buffer will be flushed as far as possible, and any invalid characters will be replaced with one or more question marks. If the buffer ends in an incomplete multibyte character, this incomplete character will be held back (since it presumably needs to be combined with later input).
