/* Takes an expression to test for SUCCESS and a message, which

may include printf-style arguments. Logs the message, then

tests the expression. If it is zero, indicating failure,

Somewhat tricky to use:
|
||
|
|
|
||
|
|
- SUCCESS must not have side effects that affect the
|
||
|
|
message, because that will cause the original message and
|
||
|
|
the failure message to differ.
|
||
|
|
|
||
|
|
- The message must not have side effects of its own, because
|
||
|
|
it will be printed twice on failure, or zero times on
|
||
|
|
success if quiet is set. */
