Is curl_global_cleanup() really necessary?

[philbond007]

Hi all,

I'm using libcurl from a library I want to offer to clients.
Now I want to statically link-in libcurl.

So evidently I will have to curl_global_init() once for the lifetime of the client .exe which will have also statically linked-in my libcode(which has statically linked libcurl).

Now I wonder if it's relevant to call curl_global_cleanup(), because when there will be no more libcurl-functionality needed, this means the process of the client .exe will have disappeared, together with its complete address space, so what is there to cleanup?

Tx.

Same question here.
Also, if curl_global_cleanup is ever called and then for some reason curl_global_init is called again with curl_multi_init and curl_easy_init, there is an obscure error.

 mbedtls_ctr_drbg_seed returned (-0x0034) CTR_DRBG - The entropy source failed

That sounds like (an mbedtls specific) bug

@awesomekosm it might be a bug in curl. Can you please try #13071

Thanks @jay, it works! I've tested your branch on mac clang version 15.0, I can do curl_global_cleanup and then curl_global_init again followed by successful curl_multi_perform.
