Question

What is the difference between:

thread_envs[i] = soap_copy(&env);

and

thread_envs[i] = soap_new();

Sould we use one of them or both?

Answer 1

From the documentation:

struct soap *soap_new()

Allocates, initializes, and returns
a pointer to a runtime environment

struct soap *soap_copy(struct soap *soap)

Allocates a new runtime environment
and copies contents of the environment
such that the new environment does not
share any data with the original
environment
