.SH NAME
vpSetClientData \- define a client data pointer
.SH SYNOPSIS
#include <volpack.h>
.sp
.FS vpResult
\fBvpSetClientData(\fIvpc, client_data\fB)\fR
.FA
vpContext *\fIvpc;\fR
.FA
void *\fIclient_data;\fR
.FE
.SH ARGUMENTS
.IP \fIvpc\fR
VolPack context from \fBvpCreateContext.\fR
.IP \fIclient_data\fR
Pointer to application-specific client data.
.SH DESCRIPTION
\fBvpSetClientData\fR is used to store a pointer to
application-specific client data in the VolPack context.  This pointer
is passed to some of the callback routines (see vpSetCallback(3)) to allow
the application to define its own state variables.  The pointer is not
used by VolPack.
.SH ERRORS
The return value is always VP_OK.
