I've spent several hours now reading documentation, a tutorial and a magazine article on perlxs and I can't get a minimal example to run. What I want to accomplish: * Write some data into a C char array in C code, e.g. like this: void set_data(char * s) { s[0] = 'a'; s[1] = 'b'; * Call that C function from a Perl module and use the String from within
