Module deprecated or moved
This module is deprecated or moved on the latest stable version. The last existing version (v2_1_10) is shown here.
A bridge to the dlopen() or dynamic library linker function.
Example
bash $> cat > sum.c <<EOF double sum(double *arry, int len) { double ret = 0; int i; for(i = 0; i < len; i++){ ret = ret + arry[i]; } return ret; } double split(double num) { double ret = 0; ret = num / 2; return ret; } EOF bash $> gcc -o libsum.so -shared sum.c bash $> cat > sum.rb <<EOF require 'dl' require 'dl/import' module LibSum extend DL::Importer dlload './libsum.so' extern 'double sum(double*, int)' extern 'double split(double)' end a = [2.0, 3.0, 4.0] sum = LibSum.sum(a.pack("d*"), a.count) p LibSum.split(sum) EOF bash $> ruby sum.rb 4.5
WIN! :-)
