[Gambas-user] Issue trying to access external Libraties

[Gareth Bult]

Mmm,

Interesting .. just calling the routine without the print no longer gives an error.

However, the documentation on the site states;

Function: virDomainGetInfo
int	virDomainGetInfo		(virDomainPtr domain, virDomainInfoPtr info)

Extract information about a domain. Note that if the connection used to get the domain is limited only a partial set of the information can be extracted.
domain:	a domain object
info:	pointer to a virDomainInfo structure allocated by the user
Returns:	0 in case of success and -1 in case of failure.

.... confused ...

In this definition the last function has no return value, so you can
not print the output of the function, as there's not any return value.

I suppose that "inf" can be s pointer which receives the information
or something like that, or may be you forgot to put the return
value...
