46 /*! \name Token Paste
\r
48 * Paste N preprocessing tokens together, these tokens being allowed to be \#defined.
\r
50 * May be used only within macros with the tokens passed as arguments if the tokens are \#defined.
\r
52 * For example, writing TPASTE2(U, WIDTH) within a macro \#defined by
\r
53 * UTYPE(WIDTH) and invoked as UTYPE(UL_WIDTH) with UL_WIDTH \#defined as 32 is
\r
54 * equivalent to writing U32.
