asic() generates necessary functions. Put this in .c files
#define asic(func, return_type, args_types...)asicDefinition() generates definitions for promise type, wait and async functions. Put this in .h files
#define asicDefinition(func, return_type, args_types...)char *read_all_file(char *filename);
asicDefinition(read_all_file, char *, char *);expands to
char *read_all_file(char *filename);
struct read_all_file_promise;
struct read_all_file_promise *read_all_file_async(char *);
char *read_all_file_promise_wait(struct read_all_file_promise *promise);- only gcc (because of use __builtin_apply_args, __builtin_apply)
- max 1024 bytes for arguments or less (idk how to calc size of args_types)
