fasttrap - DTrace user instruction tracing provider
DESCRIPTION
The fasttrap driver is a DTrace dynamic tracing provider that performs dynamic instrumentation of arbitrary instructions in Solaris pro-
cesses. The fasttrap driver implements the DTrace fasttrap and pid providers.
The fasttrap driver is not a public interface and you access 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
fasttrap provider.
SPARC ONLY
The fasttrap provider provides a DTrace probe that fires each time a user process executes an instruction. The pid provider allows for the
dynamic creation of DTrace probes corresponding to instruction locations inside any user process specified using a process ID and an
instruction address or symbol name. Together these providers permit DTrace users to perform instrumentation of Solaris user processes and
to trace the interactions between processes and the operating system. See the chapter entitled "User Process Tracing" in the Solaris
Dynamic Tracing Guide for information on how to use these providers to instrument processes.

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.
