/**

Print an error message on stderr.
|
||
|
|
Prefixed with the binary's name (sans .exe, where applicable,
|
||
|
|
and without path, both to keep our test cases sane).
|
||
|
|
The name is intended to aid debugging by clarifying which
|
||
|
|
binary reported an error, especially in cases like mysql_upgrade
|
||
|
|
which calls several other tools whose messages should be
|
||
|
|
distinguishable from each other's, and from mysql_upgrade's.
|
||
|
|
|
||
|
|
This is low-level; in most cases, you should use my_message_local()
|
||
|
|
instead (which by default goes through my_message_local_stderr(),
|
||
|
|
which is a wrapper around this function that adds a severity level).
|
||
|
|
|
||
|
|
@param error The error number. Currently unused.
|
||
|
|
@param str The message to print. Not trailing \n needed.
|
||
|
|
@param MyFlags ME_BELL to beep, or 0.
