.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is turned on, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "GCORE 1"
GCORE 1 "2016-10-07" "gdb-7.12" "GNU Development Tools"
For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
"NAME"
gcore - Generate a core file of a running program
"SYNOPSIS"
Header "SYNOPSIS" gcore [-o filename] pid
"DESCRIPTION"
Header "DESCRIPTION" Generate a core dump of a running program with process \s-1ID \s0pid. Produced file is equivalent to a kernel produced core file as if the process crashed (and if \*(C`ulimit -c\*(C' were used to set up an appropriate core dump limit). Unlike after a crash, after gcore the program remains running without any change.
"OPTIONS"
Header "OPTIONS"
"-o filename" 4
Item "-o filename" The optional argument \fIfilename specifies the file name where to put the core dump. If not specified, the file name defaults to core.pid, where pid is the running program process \s-1ID.\s0
"SEE ALSO"
Header "SEE ALSO" The full documentation for \s-1GDB\s0 is maintained as a Texinfo manual. If the \*(C`info\*(C' and \*(C`gdb\*(C' programs and \s-1GDB\s0's Texinfo documentation are properly installed at your site, the command

.Vb 1 info gdb .Ve

should give you access to the complete manual.
