Statement,

The beauty of threads is that you do not have to worry about how to do things like this. You acccess them the same way you would if you only had one thread. Please read the follwoing pseudo code.

float myArray[1000] ;
struct {
  float f ;
  char *str ;
} myStruct ;

main() {
  pthread_create(&id, threadMain....) ;

  myArray[ 23 ] = 3.14159 ;
  myStruct.f = 2.71828189 ;
  
}

threadMain() {
  myArray[ 24 ] = 3.14159/2.0 ;  /* I can access them here too */
  myStruct.f += 1.0 ;
}

Ofcourse you need to protect the data using mutex, semaphore, locks, etc... if you are manipulating the data in both threads.
