This can be quite useful +****SOMETIMES****, allowing access to system calls and library functions +from the command line. For example, there are occasions when I want +to see the struct stat for a directory entry, and want to be able to +access st_mtime values, without having to parse output from "ls -l". +A simple: + +int main(int argc, char **argv) +{ + struct stat st; + if (stat(argv[1], &st) == 0) { + printf("%lld\n", st.st_mtime); + } + exit(0); +} + +will do the job. If I was to try this by other means, I would either +have to install all of Perl, and then learn its idiosyncratic syntax, +or write a custom C program, which I would then have to compile on +each architecture I need. + +This utility relies on there being a C compiler on the target machine, +and a working dlopen(3). + +This has only, as yet, been tested on NetBSD/i386. + +Alistair G.
