strdup in c++

Hi there,

I have a program written in c++ and I wish to use a similar function to
strdup().
The reason I have problems is that the char array requires freeing to avoid
a memory leak, but I get problems using delete[];

e.g.

char *NewCharArray;

NewCharArray = strdup("Some text");

delete []NewCharArray;


Nybody have any ideas?
Thanks
Allan

std::string NewString;

NewString = "SomeText";

// delete not required.

Nybody must be some Scandinavian guy :-)

Use std::string instead of fiddling with those arrays.

You have to use free:

#include <cstdlib>
#include <cstring>
// ...
char * NewCharArray = strdup ("Hi there");
// std::strdup doesn't compile on my machine
// (macro?). Good job I never use it.
std::free (NewCharArray);

But don't do that. Use the standard string class.

That's because there is no std::strdup. strdup
is not a standard C or C++ function.

Two ideas:

1) As others have mentioned, use std::string in preference (generally) to
char*'s.

2) Remember to always delete[] what you new[], and to free() what you
malloc() (or calloc(), or strdup(), or other functions which are
documented to requrire free()ing of the memory obtained). Under the
covers, strdup() effectively calls malloc() (I don't know if this is
strictly mandated). So, in order to correctly dispose of the memory
obtained by strdup(), your code should be:

char * NewCharArray = strdup("Some text");

free(NewCharArray);

(Depressingly, I had to look up whether free needed the parens, or does
it get called like delete... It's been so long since I've used
malloc/free.... :) )

SMACK the supplier over the head if they don't use malloc/free.

Use free() to release memory allocated by strdup().

If you're using C++ you'd be far better off using std::string.

Note that 'strdup()' is not part of standard C++ (or C).

IMO the reason you're having problems is that you're using
arrays of characters (with all their traps and pitfalls) and
dynamic allocation (with its possible problems) when you should
be using the 'std::string' type to represent strings.

std::string my_strdup(const std::string& s)
{
return s;
}

void foo()
{
std::string x(my_strdup("abc"));
}

But doing this is silly, since the same effect can be
achieved with simpler (and probably more efficient)
code:

std::string s1("abc"); /* 'duplicates' "abc" in the string 's1' */

std::string s2(s1); /* 'duplicates' 's1' contents in 's2' */

s1 = s2; /* 'duplicates' 's2' contents in 's1' */

/* etc */

This name is misleading. 'NewCharArray' is not an array,
it's a pointer.

Why not simply:

char NewCharArray[] = {"Some text"};

Then you don't need this.

Yes, stop trying to use C++ to write C code. :-)

IF you need a string, the C++ library has a very
powerful and easy to use string type which is much
safer than arrays of characters and messing with
allocation and deallocation.

Of course not, since it's not a standard function. One should
follow its documentation for correct usage. This 'correct usage'
could be different among implementations.

Only if the particular implementation of 'strdup()' being
used documents to do it that way.

malloc and free are functions, so argument list must always
be enclosed in parens:

p = malloc(whatever);
free(p);

new, new[], delete, and delete[] are operators, and do
not need parens.

p = new int;
delete p;

They have to supply malloc / free. There's no telling what the
function strdup() requires because there's no such function in
standard C or C++.

Huh. Hadn't realized that. Only that every implementation I've used has
had a strdup.... oh well. Answer rephrase: check the documentation on your
particular implementation of strdup(). All of the implementations I've
used, the memory returned by strdup() needs to be free()'d. YMMV

Sure there is. It's in every man page for strdup.

Man pages do not define the C or the C++ language. The international
standards do. And they do not contain strdup. So there is no strdup in
standard C or C++.

I assume you mean "Sure there is a way of telling what strdup()
requires", not "Sure there is such a function in standard C or C++."
From the point of view of either language, there is no way to to tell,
since the function is outside the scope of the languages (and this group).

Technically, the function itself is illegal in C because it uses a
reserved name ('str' followed by a lowercase letter - reserved for
future standard library use). I don't know if this applies in C++, where
future library functions may be in std:: rather than the global namespace.

There is a clear definition of what strdup should do. If you change
that all code that uses it breaks. It's highly unlikely that anyone
will do anything different. It's a de-facto standard.

For the longest time C was a defacto standard. In fact even now, C was
for a longer time NOT a standard that it is a standard without any help
from a standards body.

Standards are great, we have so many of them !

So what if there is no international standard to cite. If you write
somthing that breaks everyone's code, you'll need a smack in the head too.

There is a clear definition of what strdup does on that system you were
looking at. There is no clear definiton of what strdup does in C or C++,
except that it is illegaly named.

If I change the function foo() all the code what uses it will break. That

At the risk of taking this fun to a higher level...

....Let's remember why we are here. C++ exists to permit scalable yet
efficient projects. For the latter cause, the compiler frequently makes you
work harder than other languages would.

To become better than just dangerous at C++, you must learn the paths thru
its mine-field; a sane-subset.

Much rhetoric on this newsgroup derives from the attitude that one must know[color=blue]

This newsgroup's greatest service is teaching that attitude.

What is in the man page for strdup? Despite whatever you are

I have been programming C since 1977. I am well aware of the history.
We've had a standard for over ten years for C. strdup is not now nor has
it ever been part of it. As a matter of fact, if you were to define a function
called strdup, you'd be in violation of the standard.

That's all very nice ... and totally meaningless in this discussion.

Disclaimer: In no way am I advocating people use strdup.

What I am saying is that it DOES EXIST and it is well known what it
should do. THEREFORE: answers to arguments about wether you need to use
new/delete or malloc/free are well defined. A corollary is that anyone
who would implement/suggest that strdup does something differently and
incompatible needs a brain adjustment.

If you can't agree with the statement above, we'll just have to agree to
disagree because right now I can't see how someone reasonable could
disagree and be reasonable.

Lifted from the man page:

The strdup() function returns a pointer to a new string which is a
duplicate of the string s. Memory for the new string is obtained with
malloc(3), and can be freed with free(3).

It is not well known in the terms of C or C++. It is only well known in
the terms of certain UNIX-like systems. If you want to persue this

Not only is it nice, it's fucking topical. Despite the fact I've been
working with UNIX and C since 1977, I've also worked with C and
C++ on a half dozen operating systems that didn't pretend to be
UNIX. If you want to drivel on about POSIX, take it to a UNIX

The world is much bigger than the C and C++ standards. Spreading
mis-information about other facets is just plain wrong.

If you wish to hold this NG as close to the C++ standard as possible
that's an admirable goal but PLEASE refrain from discussing anything
else like you have above and we'll then be able to limit the "silly
assed" logic as you so nicely put it.

The problem is that "POSIX.1++" thing doesn't exist, yet.
Anything related to C++ is, currently, fucking UNtopical
topic in a UNIX group.

The implicication was what did the man page say that had to do with the
statement that strdup isn't standard C or C++. Which is the statement
of mine you were attempting to refute with "it's in the man page."

I wrote it ambiguously ... many apologies. This is what it's meant to say.

....... restated ......
You asked what the man page says and I gave it to you. strdup() being
part of the C++ stanard or not has no bearing on this discussion and is
quite irrelevant to this thread.
........ end .......

I hope it's less ambiguous now.

The world is. This newsgroup is not. Suggesting that it is A OK to use
strdup because it exists everywhere where C or C++ exists is wrong.

It's, "Have you stopped beating your wife?".
It only works if it's a yes-no question.

And used heavily by L. Ron Hubbard, the founder of Scientology, to
demonstrate verbal oppression. I note this, because while I have read many
things in my life this question was only mentioned in his works.

Yes. Use std::string and be done with it.
