--diag_remark=tag[,tag,... ]

--diag_remark=tag[,tag,... ]

This option sets the diagnostic messages that have the specified tags to Remark severity.

The --diag_remark option behaves analogously to --diag_errors, except that the compiler sets the diagnostic messages having the specified tags to Remark severity rather than Error severity.

Note

Remarks are not displayed by default. To see remark messages, use the compiler option --remarks.

Note

This option has the #pragma equivalent #pragma diag_remark.

Show/hideSyntax

--diag_remark=tag[,tag,...]

Where:

tag[,tag,...]

is a comma-separated list of diagnostic message numbers specifying the messages whose severities are to be changed.
