dtrace

DTRACE(1)						      General Commands Manual							 DTRACE(1)

NAME

       dtrace - Dtrace compatibile user application static probe generation tool.

SYNOPSIS

       dtrace -s file [OPTIONS]

DESCRIPTION

       The dtrace command converts probe descriptions defined in file.d into a probe header file via the -h option or a probe description file via
       the -G option.

OPTIONS

       -h     generate a systemtap header file.

       -G     generate a systemtap probe definition object file.

       -o file
	      is the name of the output file.  If the -G option is given then the output file will be called file.o; if the  -h  option  is  given
	      then the output file will be called file.h.

       -C     run the cpp preprocessor on the input file when the -h option is given.

       -I file
	      give this include path to cpp when the -C option is given.

       -k     keep temporary files, for example the C language source for the -G option.

       --types
	      generate probe argument typedef information when the -h option is given.

EXAMPLES

       Systemtap is source compatible with dtrace user application static probe support.  Given a file test.d containing:
		provider sdt_probes
		{
		  probe test_0 (int type);
		  probe test_1 (struct astruct node);
		};
		struct astruct {int a; int b;};
       Then  the  command "dtrace -s test.d -G" will create the probe definition file test.o and the command "dtrace -s test.d -h" will create the
       probe header file test.h Subsequently the application can define probes using
	 #include "test.h"
	  ...
	 struct astruct s;
	  ...
	 SDT_PROBES_TEST_0(value);
	  ...
	 SDT_PROBES_TEST_1(s);

       The application is linked with "test.o" when it is built.
