       SippPixMapGetCom pixmapHandle [name] [retvar | {}]
              Return the value of comment identified by name from
              a pixmap object
               specified by pixmapHandle.  If retvar is specified
              the command returns `1' if the comment is found and
              `0' if it is not found.  The value of  the  comment
              is  returned  in the variable retvar, unless retvar
              is `{}', in which the  only  the  presence  of  the
              variable  is returned, but not value.  If retvar is
              not specified, the command returns the value of the
              comment  or  an  empty string if the comment has no
              value or is not found.  If no arguments are  speci-
              fied,   then  a  keyed  list  of  all  comments  is
              returned.
