@c man begin SYNOPSIS gcore
gcore [-o @var{filename}] @var{pid}
@c man end
@end format
@c man begin DESCRIPTION gcore
Generate a core dump of a running program with process ID @var{pid}.
Produced file is equivalent to a kernel produced core file as if the process
crashed (and if @kbd{ulimit -c} were used to set up an appropriate core dump
limit). Unlike after a crash, after @command{gcore} the program remains
running without any change.
@c man end
@c man begin OPTIONS gcore
@table @env
@item -o @var{filename}
The optional argument
@var{filename} specifies the file name where to put the core dump.
If not specified, the file name defaults to @file{core.@var{pid}},
where @var{pid} is the running program process ID.
@end table
@c man end
@c man begin SEEALSO gcore
@ifset man
The full documentation for @value{GDBN} is maintained as a Texinfo manual.
If the @code{info} and @code{gdb} programs and @value{GDBN}'s Texinfo
documentation are properly installed at your site, the command
@smallexample
info gdb
@end smallexample
@noindent
should give you access to the complete manual.
