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

  3. 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

    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

    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
