NAME
     dmBufferGetUserData, dmBufferSetUserData - get and set user data for a
     buffer

SYNOPSIS
     #include <dmedia/dm_buffer.h>

     DMstatus dmBufferGetUserData( DMbuffer buffer, u_char *data, int *size )

     DMstatus dmBufferSetUserData( DMbuffer buffer, const u_char *data, int size )

DESCRIPTION
     dmBufferGetUserData returns size bytes of user data in data.  The maximum
     size of the user data area of buffer is DM_BUFFER_MAX_AUX_DATA_SIZE.  The
     size of valid user data is set by dmBufferSetUserData.

     dmBufferSetUserData copies size bytes of data pointed to by data into the
     user data area of buffer.  If size is greater than
     DM_BUFFER_MAX_AUX_DATA_SIZE , DM_FAILURE is returned.
