Asic - easy async

Asic uses macros to generate async functions

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);

drawbacks

• 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)
