When something expects a "int *", you're not supposed to declare an "int *". That creates an empty pointer, pointing to nowhere, which will probably cause your program to crash when used!
What they want when they demand an "int *" is pointer to an integer, the address of an integer, so they can modify that integer.

Hi,
Ho do I differentiate system call from library call?
for example if I am using chmod , how do I find out if it is a system call or library call?
Thanks

Did not use 'wait' yet.
How I understand by now the wait works only for child processes, started background.
Is there any other way to watch completion of any, not related process (at least, a process, owned by the same user?)
I need to start a background process, witch will be waiting... (2 Replies)
Hi
I'm studing the system call. I've written a small program that return the time spent in doing some operations. Now I'd like to write one that return the time spent in user mode of a process.
I'm reading that i should use the tms struct:
clock_t times(struct tms *buf);
struct tms {... (2 Replies)
Hi,
I googled a bit, but could not find the answer to my problem.
But I am sure it is a common issue.
I have this code:
#!/bin/perl -w #-d
use strict;
sub remsh_test()
{
my $host = $_;
printf "\n----\n\n";
printf "remsh to $host with system call\n";
my $result = system... (3 Replies)

INTERCAL::ByteCode(3pm) User Contributed Perl Documentation INTERCAL::ByteCode(3pm)TITLE
Language::INTERCAL::Bytecode - intermediate language
DESCRIPTION
The CLC-INTERCAL compiler works by producing bytecode from the program source; this bytecode can be interpreted to execute the program
immediately; alternatively, a backend can produce something else from the bytecode, for example C or Perl source code which can then be
compiled to your computer's native object format.
The compiler itself is just some more bytecode. Thus, to produce the compiler you need a compiler compiler, and to produce that you need a
compiler compiler compiler; to produce the latter you would need a compiler compiler compiler compiler, and so on to infinity. To simplify
the programmer's life (eh?), the compiler compiler is able to compile itself, and is therefore identical to the compiler compiler compiler
(etcetera).
The programmer can start the process because a pre-compiled compiler compiler, in the form of bytecode, is provided with the CLC-INTERCAL
distribution; this compiler compiler then is able to compile all other compilers, as well as to rebuild itself if need be.
See the online manual or the HTML documentation included with the distribution for more information about this.
