You neeed syscall(SYS_tkill, ThePid, TheSignal).
Example:
#include <unistd.h>
#include <sys/syscall.h>
#include <signal.h>
int main()
{
//kills self:
pid_t tid = syscall(SYS_gettid);
syscall(SYS_tkill,tid,SIGTERM);
return 0;
}
Glibc has had a policy of not including wrappers for non-POSIX syscalls.
They may be changing it in current/future versions but using the generic syscall syscall-making function should always work on Linux.
