Hi (again) Scotty:

> you have given perl script. c program would also behave similarly, correct ?

Yes. Perl's guts are written in C and hence use standard system calls. You can see this in the 'lseek(2)' and 'truncate(2)' calls. Look at the HP-UX manpages.

Some of the standard C library functions are re-implemented in Perl's internals but the overall goal is the same. Perl's 'tell(3S)' is roughly equivalent to the C function 'ftell()'.

Hi (again) Scotty:

You can download a 'tusc' binary from the PH-UX Porting Centre. Installation is done with 'swinstall' into the '/usr/local/bin' directory:

I'm not sure. But you should trust what's on truncate(2), since Integrity HP-UX 11.31 is Unix 2003 branded.

I believe you will find what seek (no pun intended) here:
