.SH NAME
gcore \- get core image of running process
.SH SYNOPSIS
.B gcore
[\fB-s\fP][\fB-c core\fP] \fIpid\fP
.SH DESCRIPTION
.I gcore
creates a core image of each specified process,
suitable for use with
.IR adb (1).
By default the core image is written to the file \fI<pid>.core\fP.
.PP
The options are:
.TP
\fB-c\fP
Write the core file to the specified file instead of \fI<pid>.core\fP.
.TP
\fB-s\fP
Stop the process while creating the core image and resume it when done.
This makes sure that the core dump will be in a consistent state.  The 
process is resumed even if it was already stopped.  Of course, you can
obtain the same result by manually stopping the process with kill(1).
.PP
The core image name was changed from \fIcore.<pid>\fP to \fI<pid>.core\fP
to prevent matching names like \fIcore.h\fP and \fIcore.c\fP when using
programs such as \fIfind(1)\fP.
.SH FILES
<process-id>.core	The core image.
.SH BUGS
If \fBgcore\fP encounters an error while creating the core image and
the \fB-s\fP option was used the process will remain stopped.
.PP
Swapped out processes and system processes (the swapper) may not be gcore'd.
