Purpose
The #pragma warning directive allow you to suppress certain compiler warnings for a piece of code.
We support both C# style pragma warnings commands (fully) and Vulcan style pragmas (partially)
Syntax
#pragma warnings( number, state )
#pragma warnings ( pop )
#pragma warning state2 [<errornumbers>]
Note
#pragma directives must appear between before the first entity or between entities and cannot appear in the middle of an entity
Arguments
| number | Warning number to disable. Can be both numeric or in the form of XSnnnn |
| state | Off | Default Disables a warning or switches it back to the situation from the command line |
| pop | Switchs all warnings back to their default value |
| state2 | Disable | Restore Disables or restores the warning numbers that follow. When no error numbers are specified, then disable disables all warning and restore restores all warning to their default value |
| errornumbers | (Optional) comma separated list of numbers or names (XSnnnn) |
Note:
The compiler does NOT check if the numbers are valid or if they are indeed warnings. So you can specify non existent numbers and/or numbers that represent errors in stead of warnings. The compiler will not warn you when that is the case.
