I tried using unix:syslog from here 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 all

(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 all

(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.

@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.
