It is not a problem when you call realloc only few times.
It only slowed down startup when realloc was called for each fiels but I have it already fixed it.

Předmět: Re: [Wireshark-dev] Dynamically allocated field array
Hi,
Thank you, I will do it. I will also think about better solution. For example, I can write the number of fields in tpncp.dat file and perform the memory allocation only once instead of using realloc.
Thank you,
Valery.

I have already made some changes in memory allocation. Please update your source.
If it is possible to call proto_register_field_array() only once, please try it.
It is not critical for 0.99.7.
Thanks,
Tomas

Hi,
I agree it looks somewhat awkward. The TPNCP is constantly changing, so the fields are allocated dynamically by reading the tpncp.dat file at application startup. I replaced all the memory management functions with glib's analogs before submitting the patch, but I missed these two somehow, sorry. This code was written a long time ago and, as far as I remember, I had some problems passing dynamically allocated array to proto_register_field_array function, so I registered the fields one-by-one. Do you see the better solution? I will be glad to implement it. Meanwhile I will replace realloc and memcpy with glib's analogs. Is it critical for 0.99.7 release?
Thank you,
Valery.

Hi,
Yeah, and I though we're using glib functions for memory management. All
this realloc and memcpy look ugly.
Thanx,
Jaap
