Preprocessing directive like #error which doesn't stop compilation

[Alex Vinokur]

Is there any preprocessing directive like #error which doesn't stop compilation?

For instance,
# info text

Is there any preprocessing directive like #error which
doesn't stop compilation?

For instance,
# info text

There is none in standard C, but some compilers support #warning.

There is nothing defined by the C standard but some compilers offer
non-standard preprocessor directives like #warning. Additionally, some
compilers will have a #pragma option for spitting out warnings or
comments.

You'll have to check your compiler documentation or ask in a newsgroup
that would be familar with your compiler.

Even better, give up the idea. If the issue is not important enough to
warrant an #error, don't bother the user with unnecessary compilation
messages.

C does not provide a mechanism to let compilation proceed. However if
you are familiar with a bit of system programming then you can neglect
the signals (which in most cases caouse the program to abort). This is
very dangerous ...but if you are absolutely sure that you want to
block out signals then go ahead. This is done via the sigaction system
call . Take a look at the documentation for sigaction to see how to
block the signals. This is more of an OS thing rather than a C
language and is a solution for only Unix systems
