Re: Changing default alloc routines in C

Thanks for your response Burlen but in our case we want to replace malloc
and calloc in _wrap file which is generated by swig using interface file.

The custom calloc func should take size of the memory and also the string
which says the type of the structure..So that it will be useful in memory
tracking…and it will be useful in debugging memory leak even if the process
crashed. Is there a way to do this change using swig?


Thanks,

Mayank
