We have some functions such as virConnectGetType which are defined to return statically allocated strings: /** * virConnectGetType: * @conn: pointer to the hypervisor connection * * Get the name of the Hypervisor software used. * * Returns NULL in case of error, a static zero terminated string otherwise. */ const char * virConnectGetType(virConnectPtr conn) [...] This is all well and good in the typical local case, but when working over a remote connection the string we return is allocated and requires freeing at some point. Unfortunately I don't see a good thing to do in this case except to change the semantics of virConnectGetType, which arguably breaks ABI compatibility. Suggestions from anyone?
