B.2.12 -erroff[=t]
This command suppresses C compiler warning messages and has no effect on error messages. This option applies to all warning messages whether or not they have been designated by -errwarn to cause a non-zero exit status.
t is a comma-separated list that consists of one or more of the following: tag, no%tag, %all, %none. Order is important; for example, %all,no%tag suppresses all warning messages except tag. The following table lists the -erroff values:
Table B–2 The -erroff Flags|
Flag |
Meaning |
|---|---|
|
tag |
Suppresses the warning message specified by this tag. You can display the tag for a message by using the -errtags=yes option. |
|
no%tag |
Enables the warning message specified by this tag |
|
%all |
Suppresses all warning messages |
|
%none |
Enables all warning messages (default) |
The default is -erroff=%none. Specifying -erroff is equivalent to specifying -erroff=%all.
Only warning messages from the C compiler front-end that display a tag when the -errtags option is used can be suppressed with the -erroff option. You can achieve finer control over error message suppression. See 2.8.6 error_messages.
