c++ - pass the argv and argc to thread -

my program receives arguments user

int main(int argc, char *argv[]) 

and have function inside thread (i can't change function):

func (&argc, &argv); 

as can see, need call the thread, , inside thread, call func parameters. saw there way sent thread multiple parameters struct.

but how struct suppose looks like? , how copy parameters struct?

thanks!

struct arg_holder {     int argc;     char ** argv; };  void * thread_caller(void * arg) {     struct arg_holder arg_struct = *(struct arg_holder *)arg;     free(arg);     return func(arg_struct->argc, arg_struct->argv); } 

in main:

struct arg_holder * arg_struct = malloc(sizeof(*arg_struct)); arg_struct->argc = argc; arg_struct->argv = argv;  pthread_create(&thread_id, null, thread_caller, arg_struct);
