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?

Rich.
