They are pointers. This is sure. But there is some mistakes in the code I gave before. The assignment should use * before the pointers. I am sorry for carelessness when posted. But when checking with 'while ( *( tr->root->is_done ) )', the same segfault happen. And corresponding pinter address still be 'out of bounds". In my code, such statements exist.
This is a package coded by a previous member. He habits to use such structure for varialbes which control execution. A large package means that it is not easy to change all the strutures of this kind.
What's more, I think this is really a topic worth discusssion.

I hate to say this, but you seem very confused about pointers. I think you need to read a very concise summary on C pointers.
In the code you provide, you are trying to assign values to the address...
You should instead be doing:
And your loop should be:
Also, root itself is a pointer. So you first need to allocate it:
"tr" is also a pointer, and this needs to be allocated too, but I have no idea what kind of structure it is.
Also, this structure is very unusual. I cannot imagine why you want every element to be a pointer to something!
Hi,
I am trying to set up a cron job for every Friday at 6:00 p.m. and got an error:

Any ideas?

Hello, sorry if this has been posted before but i was wondering if there is a way to run a program until a segmentation fault is found.
Currently i'm using a simple shell script which runs my program 100 times, sleeps 1 second because srand(time(0)) is dependent on seconds. Is there a possible... (1 Reply)

I have a program that allows users to specify the debug log file location and name.

Could someone please point me in the direction to a function that... (1 Reply)
hello all,
my question is not about How code can be rewritten, i just wanna know even though i am not using read only memory of C (i have declared str) why this function gives me segfault :wall:and the other code executes comfortably though both code uses same pointer arithmetic.

qpsmtpd::address
Qpsmtpd::Address(3pm) User Contributed Perl Documentation Qpsmtpd::Address(3pm)NAME
Qpsmtpd::Address - Lightweight E-Mail address objects
DESCRIPTION
Based originally on cut and paste from Mail::Address and including every jot and tittle from RFC-2821/2822 on what is a legal e-mail
address for use during the SMTP transaction.
USAGE
my $rcpt = Qpsmtpd::Address->new('<email.address@example.com>');
The objects created can be used as is, since they automatically stringify to a standard form, and they have an overloaded comparison for
easy testing of values.
METHODS
new()
Can be called two ways:
o Qpsmtpd::Address->new('<full_address@example.com>')
The normal mode of operation is to pass the entire contents of the RCPT TO: command from the SMTP transaction. The value will be fully
parsed via the canonify method, using the full RFC 2821 rules.
o Qpsmtpd::Address->new("user", "host")
If the caller has already split the address from the domain/host, this mode will not canonify the input values. This is not
recommended in cases of user-generated input for that reason. This can be used to generate Qpsmtpd::Address objects for accounts like
"<postmaster>" or indeed for the bounce address "<>".
The resulting objects can be stored in arrays or used in plugins to test for equality (like in badmailfrom).
canonify()
Primarily an internal method, it is used only on the path portion of an e-mail message, as defined in RFC-2821 (this is the part inside the
angle brackets and does not include the "human readable" portion of an address). It returns a list of (local-part, domain).
parse()
Retained as a compatibility method, it is completely equivalent to new() called with a single parameter.
address()
Can be used to reset the value of an existing Q::A object, in which case it takes a parameter with or without the angle brackets.
Returns the stringified representation of the address. NOTE: does not escape any of the characters that need escaping, nor does it include
the surrounding angle brackets. For that purpose, see format.
format()
Returns the canonical stringified representation of the address. It does escape any characters requiring it (per RFC-2821/2822) and it
does include the surrounding angle brackets. It is also the default stringification operator, so the following are equivalent:
print $rcpt->format();
print $rcpt;
user([$user])
Returns the "localpart" of the address, per RFC-2821, or the portion before the '@' sign.
If called with one parameter, the localpart is set and the new value is returned.
host([$host])
Returns the "domain" part of the address, per RFC-2821, or the portion after the '@' sign.
If called with one parameter, the domain is set and the new value is returned.
notes($key[,$value])
Get or set a note on the address. This is a piece of data that you wish to attach to the address and read somewhere else. For example you
can use this to pass data between plugins.
