A new package RcppGetconf to read system configuration --- not unlike getconf from the libc library. Now R can read what system calls sysconf, pathconf and confstr have to say. The package is still pretty green, and now on CRAN in a very first version, corresponding to a very first (and single !) commit.
Right now, the CRAN just has one function getAll() similar to getconf -a. A first example shows how it provides all values which can be retried -- currently 320 on my systems.
R> res <- getAll()
R> head(res)
key value type
1 LINK_MAX 65000 path
2 _POSIX_LINK_MAX 65000 path
3 MAX_CANON 255 path
4 _POSIX_MAX_CANON 255 path
5 MAX_INPUT 255 path
6 _POSIX_MAX_INPUT 255 path
R> tail(res)
key value type
315 LEVEL4_CACHE_ASSOC 0 sys
316 LEVEL4_CACHE_LINESIZE 0 sys
317 IPV6 200809 sys
318 RAW_SOCKETS 200809 sys
319 _POSIX_IPV6 200809 sys
320 _POSIX_RAW_SOCKETS 200809 sys
R> Earlier this evening I added a second function to the GitHub repo which can access indivial values.
But right now, the biggest need is really for someone with some systems skills---and an OS X machine---to look at the code, and maybe the getconf.c from the C library, in order to make this build OS X. If you can help, please get in touch.
More about the package is at the local RcppGetconf page and the GitHub repo.
