36 .Nd get core images of running process
47 utility creates a core image of the specified process,
50 By default, the core is written to the file
52 The process identifier,
54 must be given on the command line.
55 If no executable image is
59 .Dq Pa /proc/<pid>/file .
61 The following options are available:
62 .Bl -tag -width indent
64 Write the core file to the specified file instead of
67 Tells gcore to skip map segments larger than the specified
69 Specify a suffix 'k', 'm', 'g', or 't' for kilobytes, etc.
70 Segments ignored due to the option will be reported.
72 Stop the process while gathering the core image, and resume it
74 This guarantees that the resulting core dump will be in a consistent state.
75 The process is resumed even if it was already stopped.
76 The same effect can be achieved manually with
79 Verbosely print out the map segments being dumped.
