unix.lsp / unix:syslog, example please

[Darth_Severus]

I tried using unix:syslog from here http://www.newlisp.org/code/modules/unix.lsp.html">http://www.newlisp.org/code/modules/unix.lsp.html



I don't know what printf format means, though I read the wikipedia entry.



All of these examples

Code Select Expand

(module "unix.lsp") (unix:syslog 5 "test %s")
(module "unix.lsp") (unix:syslog 5 "test%s")
(module "unix.lsp") (unix:syslog 5 "%s test")
(module "unix.lsp") (unix:syslog 5 "test" "%s")
(module "unix.lsp") (unix:syslog 5 "%s" "test")
give me a Segmentation fault, others as well.



I already added "/usr/lib/i386-linux-gnu/libc.so" ; Linux

to /usr/local/share/newlisp-10.6.2/modules/unix.ls

Which version of Linux?

Seems it gets somewhat happier including %d and %m in the format; i.e.

Code Select Expand

(unix:syslog 5 "%d %m")
Doing so at least avoids the vprintf crash (Ubuntu 14.04.3 64bit), but the message is still garbled.



Basically, from experimenting it appears that the format string can be without indicators, or it should include %d as first indicator,  and then optionally %m, which results in the system error string.



The first syslog argument doesn't seem to be of much use except of making the format string the second argument. Though I haven't really explored it much.



Additional format indicators didn't seem to work too well.

Which version of Linux?

MX Linux (32 Bit)

3.14-0.bpo.2-686-pae #1 SMP Debian 3.14.15-2~bpo70+1 (2014-08-21) i686 GNU/Linux



@ralf: The string needs to be in printf, not the number.

syntax: (unix:syslog num-priority str-message ...)

parameter: num-priority - The priority of the message.

parameter: str-message - The message string and template in printf format.

It's based on Debian 8.2
