From some testing with directly using C code, pthread_t on macos is 8 bytes.
This is my test code:
```
#include <assert.h>
#include <stdio.h>
#include <pthread.h>
void* PosixThreadMainRoutine(void* data)
{
// Do some work here.
for (int i = 0; i < 2000000000; i++) {
}
return NULL;
}
pthread_t LaunchThread()
{
// Create the thread using POSIX routines.
pthread_attr_t attr;
pthread_t posixThreadID;
int returnVal;
returnVal = pthread_attr_init(&attr);
assert(!returnVal);
returnVal = pthread_attr_setdetachstate(&attr, PTHREAD_CREATE_JOINABLE);
assert(!returnVal);
int threadError = pthread_create(&posixThreadID, &attr, &PosixThreadMainRoutine, NULL);
returnVal = pthread_attr_destroy(&attr);
assert(!returnVal);
if (threadError != 0)
{
// Report an error.
}
return posixThreadID;
}
int main() {
pthread_t t = LaunchThread();
void ** ret;
printf("%d, %d\n", sizeof(t), sizeof(pthread_t));
int val = pthread_join(t, ret);
printf("%d", val);
return 0;
}
```
running this on macos reports `8, 8`.
Then I made the proposed changes and errors I was having with threads completely went away.
