Hello all,I am a learner of C and are somewhat puzzled by some code I've come
across in Allegro,namely in allegro.h where it states as follows
#define END_OF_FUNCTION(x)   x##_end(){}
I have searched through all the allegro and system includes and have not found
any reference to the expression  x##_end(){} I have been under the assumption
that for anything to be defined the expression on the right has to be some
valid expression already previously declared or defined.
I know that this query is possibly more to to do with another ng,but since its
allegros code I have posted it here,any help to enlighten me to how this works
or what it means would be much appreciated.
