TODO
|
|
The following is a small list as to what is currently wrong/suggestions for
|
|
ustdio.
|
|
|
|
* %D and %T printf uses the current timezone, but the scanf version uses GMT.
|
|
* %p should be deprecated. Pointers are 2-16 bytes big and scanf should
|
|
really read them.
|
|
* The format specification should use int32_t and ICU type variants instead of
|
|
the compiler dependent int.
|
|
* We should consider using Microsoft's wprintf and wscanf format
|
|
specification.
|
|
* %C and %S are aliases of %lc and %ls, which are used for wchar_t.
|
|
We should consider using this for UChar and replace %K and %U,
|
|
or we should make them use wchar_t.
|
|
* + in printf format specification is incomplete.
|
|
* Make sure that #, blank and precision in the printf format specification
|
|
works.
|
|
* Make sure that * in the scanf format specification works.
|
|
* Each UFILE takes up at least 2KB. This should be really reduced.
|
|
* This library does buffering. The OS should do this for us already. Check on
|
|
this, and remove it from this library, if this is the case. Double buffering
|
|
wastes a lot of time and space.
|
|
* Make sure that surrogates are supported.
|
|
* The ustream header should also include operator<< and
|
|
operator>> for UDate (not double). This may not work on some compilers
|
|
that use these operators on a double.
|
|
* Testing should be done for reading and writing multi-byte encodings,
|
|
and make sure that a character that is contained across buffer boundries
|
|
works even for incomplete characters.
|
|
* Make sure that the last character is flushed when the file/string is closed.
|
|
* snprintf should follow the C99 standard for the return value, which is
|
|
return the number of characters (excluding the trailing '\0')
|
|
which would have been written to the destination string regardless
|
|
of available space. This is like pre-flighting.
|
|
* Everything that uses %s should do what operator>> does for UnicodeString.
|
|
It should convert one byte at a time, and once a character is
|
|
converted then check to see if it's whitespace or in the scanset.
|
|
If it's whitespace or in the scanset, put all the bytes back (do nothing
|
|
for sprintf/sscanf).
|
|
* If bad string data is encountered, make sure that the function fails
|
|
without memory leaks and the unconvertable characters are valid
|
|
substitution or are escaped characters.
|
|
* u_fungetc() can't unget a character when it's at the beginning of the
|
|
internal conversion buffer, and it shouldn't be writing new
|
|
characters to this buffer because they might be different characters.
|
|
This can be tested by writing a file, and reading it backwards by
|
|
using u_fgetc and two u_fungetc() calls with incorrect data.
|
|
FYI The behavior is undefined for ungetc() when an incorrect character
|
|
is put back, when its called multiple times in a row, or when
|
|
a its called without a read operation.
|
|
* u_fflush() and u_fclose should return an int32_t like C99 functions.
|
|
0 is returned if the operation was successful and EOF otherwise.
|
|
* u_fsettransliterator does not support U_READ side of transliteration.
|
|
* The format specifier should limit the size of a format or honor it in
|
|
order to prevent buffer overruns. (e.g. %1000.1000d).
|
|
* More testing is needed.
