Returns the actual time in milliseconds with an arbitrary origin. This time may only be used to calculate relative times. Overruns in the 32 bit value don't hurt since in a subtraction calculated with 32 bit accuracy this overrun cancels (you may think about!).. ... DWORD start, stop: start = ss_millitime(); < do operations > stop = ss_millitime(); printf("Operation took %1.3lf seconds\n",(stop-start)/1000.0); ...

Suspend the calling process for a certain time. The function is similar to the sleep() function, but has a resolution of one milliseconds. Under VxWorks the resolution is 1/60 of a second. It uses the socket select() function with a time-out. See examples in ss_time()

Creates and returns a new thread of execution. Note the difference when calling from vxWorks versus Linux and Windows. The parameter pointer for a vxWorks call is a VX_TASK_SPAWN structure, whereas for Linux and Windows it is a void pointer. Early versions returned SS_SUCCESS or SS_NO_THREAD instead of thread ID. Example for VxWorks ...
VX_TASK_SPAWN tsWatch = {"Watchdog", 100, 0, 2000, (int) pDevice, 0, 0, 0, 0, 0, 0, 0, 0 ,0};
midas_thread_t thread_id = ss_thread_create((void *) taskWatch, &tsWatch);
if (thread_id == 0) {
printf("cannot spawn taskWatch\n");
}
...
... midas_thread_t thread_id = ss_thread_create((void *) taskWatch, pDevice); if (thread_id == 0) { printf("cannot spawn taskWatch\n"); } ...

Destroys the thread identified by the passed thread id. The thread id is returned by ss_thread_create() on creation.
... midas_thread_t thread_id = ss_thread_create((void *) taskWatch, pDevice); if (thread_id == 0) { printf("cannot spawn taskWatch\n"); } ... ss_thread_kill(thread_id); ...
