/* If P is null, allocate a block of at least *PN such objects;
otherwise, reallocate P so that it contains more than *PN objects
each of S bytes. *PN must be nonzero unless P is null, and S must
be nonzero. Set *PN to the new number of objects, and return the
pointer to the new block. *PN is never set to zero, and the
returned pointer is never null.
Repeated reallocations are guaranteed to make progress, either by
allocating an initial block with a nonzero size, or by allocating a
larger block.
In the following implementation, nonzero sizes are increased by a
factor of approximately 1.5 so that repeated reallocations have
O(N) overall cost rather than O(N**2) cost, but the
specification for this function does not guarantee that rate.
Here is an example of use:
int *p = NULL;
size_t used = 0;
size_t allocated = 0;
void
append_int (int value)
{
if (used == allocated)
p = x2nrealloc (p, &allocated, sizeof *p);
p[used++] = value;
}
This causes x2nrealloc to allocate a block of some nonzero size the
first time it is called.
To have finer-grained control over the initial size, set *PN to a
nonzero value before calling this function with P == NULL. For
example:
int *p = NULL;
size_t used = 0;
size_t allocated = 0;
size_t allocated1 = 1000;
void
append_int (int value)
{
if (used == allocated)
{
p = x2nrealloc (p, &allocated1, sizeof *p);
allocated = allocated1;
}
p[used++] = value;
}
*/

size_t n = *pn;
if (! p)

/* The approximate size to use for initial small allocation
requests, when the invoking code specifies an old size of

If memory debugging is not turned on, xmalloc.h defines these:

#define xrealloc checking_realloc
#define xstrdup checking_strdup
#define xfree checking_free
In case of memory debugging, the definitions are a bit more
complex, because we want to provide more information, *and* we want
to call the debugging code. (The former is the reason why xmalloc
and friends need to be macros in the first place.) Then it looks
like this:

#define xmalloc0(a) debugging_malloc0 (a, __FILE__, __LINE__)

#define xstrdup(a) debugging_strdup (a, __FILE__, __LINE__)

simply have xfree() do nothing if ptr==NULL.)
Since the code is already written that way, this assert simply
enforces the existing constraint. The benefit is double-checking
the logic: code that thinks it can't be passed a NULL pointer,
while it in fact can, aborts here. If you trip on this, either
the code has a pointer handling bug or should have called
xfree_null instead of xfree. Correctly written code should never
trigger this assertion.
The downside is that the uninitiated might not expect xfree(NULL)
to abort. If the assertion proves to be too much of a hassle, it
can be removed and a check that makes NULL a no-op placed in its
