ciabatta/todo.md

general:

• Start writing documentation concerning various implementation defined behaviours of the library.
• (MSVC Ext.) Different kinds of main functions: wmain, WinMain, wWinMain, DllMain
• (MSVC Ext.) envp argument for main functions

math.h:

• exp
• exp2
• expml
• log
• log10
• log2
• log1p
• pow
• cbrt
• hypot
• atan2
• erf
• erfc
• tgamma
• lgamma
• frexp
• ldexp
• M_* constants
• M_E
• M_LOG2
• M_LOG10
• other stuff?

stdint.h:

• Implement 7.20.3

stdio.h:

• The only reason to keep a linked list of all streams is to make sure they are flushed after main() returns. I wonder if only remembering the files with a buffer would increase performance.
• Formatted scan
• %s precision should specify how much characters to write
• %s check for NULL
• %Ls this is an actual weird territory. If (wchar_t *) is a unicode string then to determine it's "width" (to figure out field padding) would require to use a Unicode composition algorithm. But the problem is that windows Unicode rendering advances text by 2 units, even if it's 1 graphical character that was composed from 2 unicode characters. The question becomes: do we implement the thing correctly by using a more complex solution, or do we succumb to windows' bullshittery. I guess the answer is obvious. That's why I wrote this todo item :D
• tmpfile
• tmpnam
• tmpfile_s
• tmpnam_s
• Printing 8.98846567431157854073e+307
• Printing negative zero
• Add functions for testing a file path, creating directories
• Fix the bug where if a file wasn't closed the thing crashes when trying to flush the buffer

stdlib.h:

• Strtod base 16 must be correctly rounded
• Multibyte string functions
• Better PRNG
• Fix aligned_malloc
• Constraint Handlers
• getenv_s
• aligned_alloc can't be used with free()

string.h:

• strnlen_s
• memset_s
• memmove_s
• memcpy_s
• strncpy_s
• strcpy_s
• strcat_s
• strncat_s
• strtok_s
• strerror_s
• strerrorlen_s

tgmath.h:

• Due to the use of conditional operator in type-generic macros the expression always expands to the value of type long double. This leads to warnings when used with printf, e.g. as in printf("%f\n", exp(0)). Using _Generic macros isn't a good choice either, because it won't work with typedef'd types. In other words there's no pure-C way to do tgmath.h. That's probably the reason msvc stdlib headers don't implement tgmath.h. clang implements it with attribute((overloadable)).

threads.h:

• TODO: add todo items

time.h:

• Probably some other funcs
• asctime_s
• ctime_s
• gmtime_s
• localtime_s

wchar.h:

• Collation, IO, Tokenization, Conversions
