### Condition

### Overview

- Condition wrapper.
- Provides passing data between signal and wait threads.
- Normally, if no thread waits on a condition, signal is missed. This  
  implementation differs as it will keep a result variable when 'signal' is  
  called. Signal will mark the condition 'done', so when another thread calls  
  wait(), it won't be blocked, it will return immediately with the user  
  provided data.

### Usage

```c
#include "sc_cond.h"

#include <stdio.h>

int main()
{
    struct sc_cond cond;

    sc_cond_init(&cond); // Init once
    
    sc_cond_signal(&cond, "test"); // Call this on thread-1
    char* p = sc_cond_wait(&cond); // Call this on another thread.

    printf("%s \n", p); // Prints "test"
    
    sc_cond_term(&cond); // Destroy

    return 0;
}

```
