...or using the function call in an 'if' conditional, the way the compiler warning would want us to do it). Many of the uses in libvirt code base are things like this in src/conf/domain_addr.c: char * virDomainPCIAddressAsString(virPCIDeviceAddressPtr addr) { char *str; ignore_value(virAsprintf(&str, "%.4x:%.2x:%.2x.%.1x", addr->domain, addr->bus, addr->slot, addr->function)); return str; } We intentionally marked virAsprintf() as requiring the...
