Carp the code:

const char *
clog_identify(uint8 info)
{
switch (info)
{
case CLOG_ZEROPAGE:
return "ZEROPAGE";
case CLOG_TRUNCATE:
return "TRUNCATE";
break;
}
return NULL;
}

or

const char *
clog_identify(uint8 info)
{
if(info==CLOG_ZEROPAGE)return "ZEROPAGE";
if(info==CLOG_TRUNCATE)return "TRUNCATE";
return NULL;
}

is a bit faster than:

const char *
clog_identify(uint8 info)
{
const char *id = NULL;

switch (info)
{
case CLOG_ZEROPAGE:
id = "ZEROPAGE";
break;
case CLOG_TRUNCATE:
id = "TRUNCATE";
break;
}

return id;
}
