Hi,
I'm building an n x n 2D array.
I've declared the structure:
int ** aoa;
I've allocated the memory:
Newz(100, aoa, n, int);
if(aoa == NULL) croak("Failed to allocate rows");
for(i = 0; i < n; ++i) {
Newz(i, aoa[i], n, int);
if(aoa[i] == NULL) croak("Failed to allocate columns");
}
I've successfully placed (and accessed) data in the structure, so I guess
I've done it correctly so far.
To free the memory I've done:
for(i = 0; i < n; ++i) Safefree(aoa[i]);
But there's still some more memory to Safefree() isn't there ?
I tried adding:
Safefree(aoa);
But that crashes the program. What do I need to do ?
Also, as regards the first argument supplied to New() - is there any reason
that it should be different (ie unique) for each 'New()' call within a
program ?
I'm working on Win2k, perl5.6.1, and writing code to be used with Inline C
.... if any of that makes any difference. (I don't think it does :-)
Cheers,
Rob
