libUTIL.a - A/UX library
- Thread starter ChristTrekker
- Start date
It's a collection of functions not supplied by the A/UX system, to make porting of apps easier.
That doesn't narrow it down much. I've generally found A/UX "complete" in terms of what a classic non-threaded UNIX box is supposed to provide.
It's not ANSI and is missing a ton of prototypes, this is my work-in-progress to allow gcc with "-Wall -Werror". I extend this based on the A/UX man pages.
Code:

wctomb.oThe two libraries I use on A/UX are libbsd.a and libposix.a.
There is alot of duplication in what you listed with what A/UX libc.a (or is it libc_s) already provide. Eg, the fopen/fread/malloc.
For snprintf and memmove one should have a general strategy for when these are not provided, eg SunOS 4.1 does not have these.
You can't really provide vfork if the OS does not provide it, the classic approach is to simply use fork.
The biggest thing missing is A/UX does not have mmap, hence demand loadable shared libraries are not possible.

There is some duplication with libc ... various sources state the A/UX version is broken or deficient in some way, and the libUTIL versions are improvements.
Would you say that as a general rule it's good practice to compile everything -lbsd -lposix, then? Kind of "when in doubt, link it"?
I do, because my "portable standard" is posix. If the platform is missing something then I use a work around or provide the function.
eg
Code:
#ifdef HAVE_SNPRINTF
snprintf(buf,sizeof(buf),"...."
#else
sprintf(buf,".....
#endifAdmittedly because A/UX applications are generally is statically linked you don't have to worry about compatibility with 3rd party shared libraries over time.
There is nothing to stop you getting the glibc source and compiling a static c library from that.
I don't recall off the top of my head. Maybe it wasn't so much broken as missing (memmove, etc). I can't find any references to broken implementations now that I look for them...
BTW, sounds like you've done a fair amount of A/UX coding!
