cdecl is your friend.

~ $ cdecl 
Type `help' or `?' for help
cdecl> explain int *volatile x
declare x as volatile pointer to int
cdecl> explain volatile int *x
declare x as pointer to volatile int
cdecl> explain int (*(*(*b)())(int (*(*)())()))()
declare b as pointer to function returning pointer to function (pointer to function returning pointer to function returning int) returning pointer to function returning int
