Preprocessor - Token Paste

Token Paste
Paste N preprocessing tokens together, these tokens being allowed to be #defined. May be used only within macros with the tokens passed as arguments if the tokens are #defined. For example, writing TPASTE2(U, WIDTH) within a macro #defined by UTYPE(WIDTH) and invoked as UTYPE(UL_WIDTH) with UL_WIDTH #defined as 32 is equivalent to writing U32.
#define	TPASTE2(a, b)   a##b
#define	TPASTE3(a, b, c)   a##b##c
#define	TPASTE4(a, b, c, d)   a##b##c##d
#define	TPASTE5(a, b, c, d, e)   a##b##c##d##e
#define	TPASTE6(a, b, c, d, e, f)   a##b##c##d##e##f
#define	TPASTE7(a, b, c, d, e, f, g)   a##b##c##d##e##f##g
#define	TPASTE8(a, b, c, d, e, f, g, h)   a##b##c##d##e##f##g##h
#define	TPASTE9(a, b, c, d, e, f, g, h, i)   a##b##c##d##e##f##g##h##i
#define	TPASTE10(a, b, c, d, e, f, g, h, i, j)   a##b##c##d##e##f##g##h##i##j

Absolute Token Paste
Paste N preprocessing tokens together, these tokens being allowed to be #defined. No restriction of use if the tokens are #defined. For example, writing ATPASTE2(U, UL_WIDTH) anywhere with UL_WIDTH #defined as 32 is equivalent to writing U32.
