I'm getting the following compiler warning:
implicit function declaration: gettimeofday.

I have
#include <sys/time.h>
in my .c file

Is there something that I am missing like anohter #include

That should be all you need (it's what the man page says).

What OS version? What compiler, and version? Can you provide a minimal
test program that demonstrates this behaviour?

Solaris 10, newly installed. Don't know what cc version I have. What
ever came with Solaris 10.

I'm a newbie with Solaris,

There isn't a version of cc supplied with Solaris 10, you must have
installed one. Anyway, does this compile cleanly, it should:

#include <sys/time.h>

int main(void)
{
struct timeval tp;

gettimeofday( &tp , NULL );
}

This did compile with no problems. However, when I added -D_KERNEL, I
got the compile warning: implicit function declaration: gettimeofday.

Does this mean I shouldn't use gettimeofday in a kernel driver?
