NAME
     systrace - DTrace system call tracing provider

DESCRIPTION
     The systrace driver implements the  DTrace  syscall  dynamic
     tracing  provider.  The  syscall  provider  performs dynamic
     instrumentation to offer probes that fire whenever a  thread
     enters or returns from a kernel system call entry point.


     The systrace driver is not a public interface and you access
     the instrumentation offered by this provider through DTrace.
     Refer to the Solaris Dynamic Tracing Guide for a description
     of the public documented interfaces available for the DTrace
     facility and the probes offered by the syscall provider.
