/*
|
|
|
|
|
* The set-error SDT probe is extra static, in that we declare its fake
|
|
|
|
|
* function literally, rather than with the DTRACE_PROBE1() macro. This is
|
|
|
|
|
* necessary so that SET_ERROR() can evaluate to a value, which wouldn't
|
|
|
|
|
* be possible if it required multiple statements (to declare the function
|
|
|
|
|
* and then call it).
|
|
|
|
|
*
|
|
|
|
|
* SET_ERROR() uses the comma operator so that it can be used without much
|
|
|
|
|
* additional code. For example, "return (EINVAL);" becomes
|
|
|
|
|
* "return (SET_ERROR(EINVAL));". Note that the argument will be evaluated
|
|
|
|
|
* twice, so it should not have side effects (e.g. something like:
|
|
|
|
|
* "return (SET_ERROR(log_error(EINVAL, info)));" would log the error twice).
