A POSIX thread or p-thread is a light-weight process which is tied directly to another parent process.
As a result these p-threads all share the same region of memory.
API
Creation
A p-thread can be created with the following C API function definition:
#include <pthread.h>
// Start a new pthread
int pthread_create(
pthread_t *thread, // the returned thread index
const pthread_attr_t *attr, // thread settings
void *(*start_routine)(void*), // the function to run in the thread
void *arg // arguments to pass to the thread
);Wait on a thread
A p-thread can be blocked on with the following C API function definition:
#include <pthread.h>
// Start a new pthread
int pthread_join(
pthread_t thread, // the thread to wait on
void **value_ptr // pointer to the outputs returned by the thread
);Exit a thread
A p-thread can be exited with the following C API function definition:
#include <pthread.h>
// Start a new pthread
int pthread_exit(
void *value // the data to return to the awaiter
);
