Is there a way to disable all warnings with a pragma?

Question

I\'ve started a new project and have decided to make sure it builds cleanly with the /Wall option enabled. The only problem is not all 3rd party libraries (like boost) compi

Answer 1

Using the technique described in the Assaf Lavie's answer it is possible to create helper macros:

#define DISABLE_ALL_WARNINGS_BEGIN \
    __pragma(warning(push, 0))

#define DISABLE_ALL_WARNINGS_END \
    __pragma(warning(pop))

They can be used in the following way (online demo):

DISABLE_ALL_WARNINGS_BEGIN
void foo(int a)
{
    // this function should generate the following warning
    // "warning C4100: 'a': unreferenced formal parameter"
    // unless it is wrapped inside "DISABLE_ALL_WARNINGS" section
}
DISABLE_ALL_WARNINGS_END
