#define P99_IF_EQ (   A,   B  )    P00_IF_CLAUSE(P99_PASTE4(P00_IS_,A,_EQ_,B)()) Test two words A and B if they are equal. A and B must be just one word, i.e composed of alpha-numerical characters and underscores. For such a test to work properly a corresponding macro P00_IS_A_EQ_A must exist for all A such that B may be the same word as A. E.g for the test P99_IF_EQ(0, X)(expand_when_equal)(expand_when_unequal) the macro ::P00_IF_0_EQ_0 must exist. (Which it does in that case). Definition at line 83 of file p99_if.h.
