Being informed about the mailing list archive correct link, I searched for messages about this but didn't find something (it's possible I've missed something though).
I'm writing an external and I want to use an @ argument (for example "@sync hard"). How does one implement this in C code?

either use flext (but then you write C++) and it comes for free.
or simply iterate over the arguments, looking for symbols starting with "@" (or simply search for symbols that are "@sync"), then check whether there's another argument after that and see which value it has.

Sounds logical and simple. Will go for that.
that's how we do all "@" arguments in cyclone :)

hello,
the CicmWrapper offer convinient way to declare and manage attribute (aka @ arguments) inspired by the C74 SDK take a look at : https://github.com/cicm/cicmwrapper there are some forks on github that add / fix some things

Coming back to this thread after some time.
I'm trying to check whether a given argument to an external I'm writing starts with "@" or if it is actually "@sync", but can't seem to make it work. Can't really understand how t_symbol works. I'm iterating though the arguments with int argc and t_atom *argv and if there are the right number of arguments, I'm retrieving the argument that's supposed to be "@sync" with atom_gensym(argv);
I don't know how to compare that to a hard-coded string, like "@", or "@sync". I tried comparing straight to these strings, tried strcmp(), but I don't know how to do this, and couldn't find examples online.
Any hints?

Hi Alexandros
You can compare symbols for string equality by pointer equality (because symbols are interned in a table and never released - fast equality check is the whole point of symbols in Pd).
Something like this (untested):
static t_symbol *s_at_sync = 0; extern void foo_setup(void) { s_at_sync = gensym("@sync"); ... }
void *foo_new(int argc, t_atom *argv) { if (atom_getsym(argv[3]) == s_at_sync) { sync(); } ... }
Or you can get the pointer to the symbol's string from the symbol struct, see m_pd.h for details. You must not modify the string, but you could access it to see if it starts with '@' for example.
