#include <stdio.h>
int tst(int len,char str[1024]){
printf("called c from perl len:'%i'  str:'%s'  \n",len, str);
return 1;
}
int main(  ){
tst(54,"char");
return 1;
}

then what's wrong here, in C it works well, module for perl compiled well, but this

use TST;
TST::test(4444,"ss");

prints called c from perl len:'4444'  str:'(null)'
