Functions cannot be dynamically allocated in C. C does not have first-class functions. If arrays and structures couldn't be dynamically allocated in C, would you call C arrays and structs first class? The comparison between C arrays and functions is interesting: If C arrays were limited to the same allocations permitted to functions, all arrays would be global static variables and no more arrays could be created at runtime. I have serious doubts about whether you would know what to do with dynamically allocated functions if you had them. -- Doug Quale quale@picard.cs.wisc.edu
