In short words, I want to do (void*)0x78000000 in Perl, a pointer to a address defiend by myself (without the help of C :-P). I've searched CPAN for XS and pointers but did not found anything related to my problem
Did you come across Sys::Mmap's hardwire() method in your travels?
Just reading the synopsis for this function:
hardwire(VARIABLE, ADDRESS, LENGTH)
Specifies the address in memory of a variable, possibly within a
region you've "mmap()"ed another variable to. You must use the same
precautions to keep the variable from being reallocated, and use
"substr()" with an exact length. If you "munmap()" a region that a
"hardwire()"ed variable lives in, the "hardwire()"ed variable will
not automatically be "undef"ed. You must do this manually.
..and thought it just might be of use. Maybe try:
use Sys::Mmap;
# ...
Sys::Mmap::hardwire($address, 0x78000000, $kernel_size);
