pthread_create...

hi

is there a way to pass 2 parameter to pthread_create?

Code:

typedef struct bproduction_s {
  ....
} bproduction_t;
bproduction_t bprod;
production_t prod;

i would like to do somelthing like: 

rc = pthread_create(&threads, NULL, (void *)&writeFile, (void *)&bprod;, (void *)&prod)
if (rc) {
    printf"**CRITICAL** return code from pthread_create() is %d\n", rc);
    exit(-1);
 }

thanks

nope, define a new struct and put them both into that one new struct and pass the new struct.

ok if write:

bproduction_t bprod[2];
that will be ok?

hi

somebody can confirm me that pthread_create that onle the first parameters of the function... and will be able to know if there are some other?

Code:

void
production(production_count_t *prod_cnt, tiny_xcs_t *xcs)
{
.......
} 

int main()
{
  tiny_xcs_t xcs;
  production_count_t prod_cnt;
  rc = pthread_create(&threads, NULL, (void *)&production, (void *)&prod_cnt);
  if (rc) {
      gmacc_syslog("**CRITICAL** return code from pthread_create() is %d\n", rc);
      exit(-1);
  }
}

thanks
