Copies the field's internal string to the buffer. It copies the data in the field into the buffer, for as many bytes as the field contains, or the size of buffer, whichever is smaller.

Copies the contents of the field into the supplied buffer, up to the number of characters specified; for fields with multiple entries, the optional third parameter indicates which of the fields to retrieve. Performs similarly as the ASCII Get(char *, size_t, size_t) method, taking a unicode_t string as a parameter rather than an ascii string. The maxChars parameter still represents the maximum number of characters, not bytes.
unicode_t myBuffer[1024]; size_t charsUsed = myFrame.GetField(ID3FN_UNICODE)->Get(buffer, 1024);

Copies the contents of the field into the supplied buffer, up to the number of characters specified; for fields with multiple entries, the optional third parameter indicates which of the fields to retrieve. The third parameter is useful when using text lists (see Add(const char*) for more details). The default value for this third parameter is 1, which returns the entire string if the field contains only one item. It returns the number of characters (not bytes necessarily, and not including any NULL terminator) of the supplied buffer that are now used.
char myBuffer[1024]; size_t charsUsed = myFrame.GetField(ID3FN_TEXT)->Get(buffer, 1024); It fills the buffer with as much data from the field as is present in the field, or as large as the buffer, whichever is smaller.
char myBuffer[1024]; size_t charsUsed = myFrame.GetField(ID3FN_TEXT)->Get(buffer, 1024, 3); This fills the buffer with up to the first 1024 characters from the third element of the text list.

Returns the size of a field. The value returned is dependent on the type of the field. For ASCII strings, this returns the number of characters in the field, not including any NULL-terminator. The same holds true for Unicode---it returns the number of characters in the field, not bytes, and this does not include the Unicode BOM, which isn't put in a Unicode string obtained by the Get(unicode_t*, size_t, size_t) method anyway. For binary and integer fields, this returns the number of bytes in the field.
