Category

Pragma equivalent

Purpose

Syntax

Defaults

NOSEVERITY

When NOSEVERITY is in effect, all the previous message severity changes are cleared.

Parameters

I
Specifies the message severity level of informational (I).
W
Specifies the message severity level of warning (W).
E
Specifies the message severity level of error (E).
Message Number
Represents a valid compiler message number, which must be in the following format:

abc****

Where:
  • abc is the three-letter code prefix representing the message types.
  • **** is the four-digit message number.

Usage

The SEVERITY option allows you to set the severity for certain messages that you specified. The compiler will use the new severity if the specified messages are generated by the compiler. You can use this option to match your build process rules for cases which are known not to be problems.

The new severity can be higher or lower than the default compiler severity. When you decrease message severities, you can only decrease informational (I) and warning (W) messages. The (E) level messages cannot be decreased.

Note: When multiple severities are specified for one message, the last valid severity specified on the command line takes precedence over any previous valid specifications.

Predefined macros

None.

Examples

If your program prototype.c normally results in the following output: 
WARNING CCN3304 ./prototype.c:2 No function prototype given for "malloc".
You can decrease the severity of the message to INFORMATIONAL by compiling with: 
xlc prototype.c -qseverity=i=CCN3304
