This page refers to the changes made in the 3.0.15 release of M-sim.
Release Date:
Syscalls
osf_sys_lseek does not return -1 when called on stdin, stdout or stderr on Tru64. Empirically, it appears to output the total number of characters printed for the current session.
#include <sys/types.h> #include <unistd.h> #include <iostream>
int main()
{
cout << "Weeee!" << endl; for(int i=0;i<10;i++) { off_t sval = lseek(i,0,1); cout << i << ": " << sval << endl; }
return 0;
}
On a new session:
jloew@tru64:~/syscall$ ./a.out Weeee! 0: 722 1: 730 2: 738 3: -1 4: -1 5: -1 6: -1 7: -1 8: -1 9: -1
Second execution:
jloew@tru64:~/syscall$ ./a.out Weeee! 0: 864 1: 872 2: 880 3: -1 4: -1 5: -1 6: -1 7: -1 8: -1 9: -1
The difference is consistent (typing into the command prompt and deleting it will increase this counter). This will be handled by returning an ever increasing number by M-Sim.
