Hi, In the days when I used to do "heavy duty" coding I maintained a library of "useful" routines. A printf library was one of these: I worked through the source code of about 6 or 7 different run-time libraries to get ideas.
I have no idea what I did with it - but I can recommend the constructioin of such a library as a good learning exercise, especially if you are a freelancer working on different platforms every few months. I also learned how huge a full printf library can be! regards, Richard ----- Original Message ----- From: <nobo...@web.de> To: <mspgcc-users@lists.sourceforge.net> Sent: Sunday, April 11, 2004 9:24 PM Subject: Re: [Mspgcc-users] sprintf( "%f" > Hi, > > with other compilers you have usually more problems: The 1.26A version from > IAR (90% of the code in the company i'm working is done only for that compiler) does not know how to sprintf/sscanf %hu or %u (and maybe %f, i didn't tested it) and some simple things like including from subdirectorys or simple C99 features like the restrict qualifier do not work.
