Re: Calling C functions

Never mind.
As per docs

Code: Select all

(set 'hostname (dup "\000" 64))
(set 'lpNum (pack "lu" (length str)))
(gethostname str lpNum)
(trim str)

Calling C functions

Code: Select all

char hostname[128];
gethostname(hostname, sizeof hostname);
> (import "libnsl.so.1" "gethostname")
> gethostname<FEFC95F0>

> (set 'hostname nil)
> (gethostname hostname)
0

How to handle to the sizeof part?

Re: parsing large files (> 5GB)

That still seems very slow.

Yes they(UltraSparc iii) are slow. They belong to the 2001 era. SUN(now Oracle) sparcs are generally not optimized for single threaded performance. Infact the SPARC cpus did even feature out-out-order execution until recently.

Re: parsing large files (> 5GB)

Now using the stdin method for the original script it went down from 8 minutes to 13 secs. Phew.

Code: Select all

time ./apache.lsp < xaa
3885

real    0m13.088s
user    0m12.662s
sys     0m0.243s

Looks like fgetc method is a bad idea.

Hmm..

$ ./readstdin < test.txt

This is a Ultrasparc 25.

Re: parsing large files (> 5GB)

The difference is really huge 8 Minutes in newlisp vs 2 seconds in Perl for a 100MB log file. I am not a fan of Perl. But i am forced to use it because of its text processing performance. $ time ./apache.lsp xaa 3885 real 8m2.346s user 1m28.495s sys 6m30.581s $ cat apache.lsp ;(set 'yesterd (date (d...

Re: nth-set in Ubuntu Linux

Thank you all for the quick response. It's one of those things which makes me interested in newlisp.

It seems i was reading Aug 2008 version 'Intro to newlisp' which had the nth-set.
Its not there in Dec 2008 version anymore.

Thanks for the quick response which works.
