"I've been writing C for quite some time, but I never followed good conventions I'm afraid, and I never payed much attention to the optimization tricks of the higher C programmers. Sure, I use const when I can, I use the pointer methods for manual string copying, I even use register for all the good that does with modern compilers, but now, I'm trying to write a C-string handling library for personal use, but I need speed, and I really don't want to use inline ASM. So, I am wondering, what would other Soylenters do to write efficient, pure, standards-compliant C?"
"Steal" in quotes of course. For string libraries? I'd seek out the best Free/Open source or find out what happens when I link against a black-box proprietary lib.
a comparison [sourceforge.net] between string libraries.
bstring seems to be GPL/BSD double licensed, you'd be able to fork under whichever you like.
Yeah, bstr is nice. Better to not fork. Wrap it in the interface you like, but leave the library itself alone. Maybe writing the one or two missing features you are looking for, but otherwise reusing existing work.
