       gcore - get core images of running processes

       gcore [-pgF] [-o filename] [-c content] process-id...

       The  gcore utility creates a core image of each specified process. By default, the name of
       the core image file for the process whose process ID is process-id is core.process-id.

       The following options are supported:

       -c content     Produces core image files with the specified content. The content  descrip-
		      tion  uses  the same tokens as in coreadm(1M). The -c option does not apply
		      to cores produced due to the -p or -g flags.

       -F	      Force. Grabs the target process even if another process has control.

       -g	      Produces core image files in the	global	core  file  repository	with  the
		      global  content as configured by coreadm(1M). The command fails if the user
		      does not have permissions to the global core file repository.

       -o filename    Substitutes filename in place of core as the first part of the name of  the
		      core  image  files.  filename can contain the same tokens to be expanded as
		      the paths in coreadm(1M).

       -p	      Produces a core image  file  in  the  process-specific  location	with  the
		      process-specific content for each process as configured by coreadm(1M). The
		      command fails if the user does not have permissions to the per-process core
		      file repository.

       The following operand is supported:

       process-id    process ID

       Caution	should be exercised when using the -F flag. Imposing two controlling processes on
       one victim process can lead to chaos. Safety is assured only if	the  primary  controlling
       process,  typically a debugger, has stopped the victim process and the primary controlling
       process is doing nothing at the moment of application of the proc tool in question.

       The following exit values are returned:

       0	   On success.

       non-zero    On failure, such as non-existent process ID.

       core.process-id	  core images

       See attributes(5) for descriptions of the following attributes:

       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       |Availability		     |SUNWtoo			   |
       |Interface Stability	     |See below.		   |

       The command syntax is Evolving. The Output Formats are Unstable.

       kill(1), coreadm(1M), setrlimit(2), core(4), proc(4), attributes(5)

       gcore is unaffected by the setrlimit(2) system call using the RLIMIT_CORE value.
