Wireshark-dev: Re: [Wireshark-dev] se_alloc & ep_alloc limit at 5 MB

Hi Stevem

It would be nice to used ep_alloc0(). During DICOM export, I have may small ones (<10kB) and a few big ones.
I like to treat all the same. Not using ep_alloc() I would need to figure out, where to properly release the memory,
in (or after) a tap. I'm sure I can figure it out, but it will take some time.

It would be nice, if EMEM_PACKET_CHUNK_SIZE (10MB) is a minimum size, but if more is requested, more would be allocated. And I remove the >>2 in my code, without any side effects so far.

Do you need the memory to be automatically released by Wireshark?  If 
not, use g_malloc(), which is GLib's version of malloc.  Note that 
g_malloc will cause Wireshark to terminate if there is not enough memory 
available (so it won't return NULL).  Use g_free() to free it.  You CAN 
pass g_free() a NULL pointer - it will just ignore it.
