The prof_server function is the MIG generated server handling function to handle messages from the kernel corresponding to program counter (profiling) samples. Such messages are delivered to the task or thread sample port set by task_sample or thread_sample. The prof_server function performs all necessary argument handling for this kernel message and calls the appropriate handling function. These functions must be supplied by the caller.
TRUE The message was handled and the appropriate function was called.
FALSE The message did not apply to the sample mechanism and no other action was taken.
