Hi, I *will* code the time functions and contribute them, because I need them: -asctime -difftime -probably also time_t / struct tm conversions
How should I proceed? Write the in the lib/src/pic16 directory, then update the makefiles? (then send a patch, ok) Can I copy code from the file I indicated in my previous mail? Do we need special performant code for asctime & al? what about sprintf? (ok, I can/will probably) use basic string copy operations here - do we have a working itoa? ) Regards Sebastien On Mon, Jan 11, 2010 at 11:35 AM, Philipp Klaus Krause <p...@spth.de> wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Sébastien Lorquet schrieb: > > > Why do we need device specific versions? > > Device-specific versions of library functions exist for two reasons: > > - - Compiler bugs: Some ports are not yet able to compile the library > function, so it's not used for that port (typically disabled by an > #ifdef), a device-specific version may be provided instead.
