/*
 * Let's redefine rand() by simply compiling creating an position-independent object code:
 * $ gcc -c -fPIC libmyrand.c -o libmyrand.o
 * 
 * Then create a shared library object from it:
 * $ gcc libmyrand.o -shared -o libmyrand.so
 *
 * As a last step, load this dynamic library, so the dynamic linker will link this rand(),
 * instead of the one inside the standard library:
 * $ export LD_PRELOAD=./libmyrand.so
