Preparing for Compilation

Your application must include <thread.h> for Solaris threads and <pthread.h> for POSIX threads. You should include the appropriate file for the API you are using, or both files if your application uses both thread APIs. See the pthread.h(3HEAD) man page for more information. The application must also include <errno.h>, <limits.h>, <signal.h> , <unistd.h> files.
