Profiling Isolated Sections of Code Within Source Code.

TNF data collection can also be turned on and off within user source code using the routines tnf_process_disable, tnf_process_enable, tnf_thread_disable, and tnf_thread_enable. Since these are C functions, one must call them as follows from Fortran:

call tnf_process_disable()   !$pragma c(tnf_process_disable)
call tnf_process_enable()    !$pragma c(tnf_process_enable)
call tnf_thread_disable()    !$pragma c(tnf_thread_disable)
call tnf_thread_enable()     !$pragma c(tnf_thread_enable)

Whether these functions are called from C or Fortran, one must then link with -ltnfprobe. For more information, see the Solaris man pages on these functions.
