* NEGATIVE COMPILE TEST.
|
|
*
|
|
* This file must NOT compile. It is built by the CTest entry
|
|
* `negative_format_mismatch` with -Werror, and that test is marked WILL_FAIL.
|
|
*
|
|
* What it asserts: the format attributes on the variadic wrappers are attached
|
|
* and effective. Going through a wrapper is exactly how a caller loses the
|
|
* compile-time format checking it would have had calling printf(3) directly --
|
|
* printf("%d", "str") is caught and an unattributed wrapper's equivalent is not.
|
|
* AKSL_PRINTF_FORMAT is what restores it, and this is what proves it is there.
