...'d prefer vsnprintf > over vsprintf but have no way of testing any of these options. I wrote a small program that fills a buffer[] with "abcdefghijklmnopqrstuvwxyz\0" pattern and then tries to write "0123456789" string into it. It calls either ret = vsnprintf_s(buffer, buf_size, _TRUNCATE, fmt, va); or ret = vsnprintf(buffer, buf_size, fmt, va); The results are: --------------------------------------------------------------------------- vsnprintf_s (MSVC, MinGW): buf_size = 8; ret = -1; buffer = "0123456" buf_size = 9; ret = -1;...

It would be nice to have the following function added to the speex bits... void speex_bits_read_from_buffer( SpeexBits * const bits, void * const buff, const int buf_size) { bits->bytes = (char*)buff; bits->buf_size = buf_size; bits->nbBits = buf_size << 3; bits->bytePtr = 0; bits->bitPtr = 0; bits->owner = 0; bits->overflow = 0; } ... so a bitstream can be assigned to a SpeexBits structure for proce...

From: Sylvain Gault <sylvain.gault at gmail.com> Despite having native network capabilities, UEFI 2.4 (the most widely deployed at the moment) has no native DNS resolver. I propose here an implementation more or less inspired by the one found in core/legacynet/dnsresolv.c. Since it's non-trivial, I'd like to ask for a deep review of this code. I tried to make it as strong as

Hi, I''ve got a preliminary version of the pure Ruby version of win32-dir in CVS. However, I was hoping to work out the Unicode issue. Run this: from = "C:\\test" to = "?????" Dir.mkdir(from) unless File.exists?(from) Dir.create_junction(to, from) It works, but my explorer (and dos) window shows the name garbled. I don''t think it''s a font
