#ignore_warnings macro |

Hi,
Im trying to make a macro to ignore compiler warnings:
Code: | #define WHILE_TRUE #ignore_warnings 203 while (1) { #ignore_warnings NONE
#define END_WHILE_TRUE }
WHILE_TRUE
do_something()
END_WHILE_TRUE
|
I get compiler error:
'Constant out of the valid range 0 is not 200..299'
for #ignore_warnings 203
(Ive also tried separating lines in the macro using \)
Is it that #ignore_warnings wont allow anything else except the warning number after it => this macro idea is doomed?
Thanks in advance,
John Mackenzie |

is equivalent toThe latter doesn't generate a compiler warning.
If you don't like the for-loop construction you could write your DO_WHILE macro as Code: | #define DO_WHILE for(;;) { |

Thanks ckielstra,
I never use for(;;) so hand't thought of using it!
Nice solution!

Why not just use # ignore_warnings 203,202 etc
As a pre processor directive.

He just wanted to replace:
#ignore_warnings 203
while (1)
{
#ignore_warnings NONE
with:
WHILE_TRUE
which would clean up his code, would easily port to other programs, and it would disable the warning 203 for the "while (1)" only.

It appears to be doomed as the #ignore_warnings won't allow anything else except the warning numbers and commas after it. This includes comments.
It took me a bit to figure out why the following line continued to give me the same error as John:
#ignore_warnings 203 // ignore the warning for while(TRUE) |

Exactly!!
In the end I used for(;;) instead because
a) #ignore_warnings doesnt allow anything after the number(s) on the same line
b) its cleaner. |
