If you have the Valgrind development headers, there's a very helpful
macro to accomplish just this:
#include <valgrind/valgrind.h>
if (RUNNING_ON_VALGRIND) {
... don't rely on timed signals ...
} else {
... rely on timed signals ...
}
I use that macro frequently, i.e. automatically turning on a global
debug variable, which in turn controls a bunch of other things.
So, more properly, it might be:
#if HAVE_VALGRIND_VALGRIND_H
#include <valgrind/valgrind.h>
#else
#define RUNNING_ON_VALGRIND 0
#endif
unsigned int debug_mode = 0;
int main(void)
{
if (RUNNING_ON_VALGRIND)
debug_mode = 1;
....
if (debug) {
... disable signals ...
}
}
That's probably the cheapest way to do it, unless you need the VG
instance. It sounds like you just need to know if your program is
running under VG and adjust its behavior if so.
There are a lot of other very useful bits in valgrind.h if you want to
take a peek.
