* ptask / qmem

** Abstract

- ptask: parallel task scheduler for C programmer
- qmem: thread-safe queued memory manager for C programmer

** License

Same license as Ruby (CRuby/MRI) Interpreter 1.9.3 or later.


** ptask

TBD


** qmem

*** Usage

qmem_t *qm = qmem_create(4096 * 16); // 16 pages
  // The number is buffer size.  If there are not enough buffer, 
  // allocate a buffer which size is this number.

...
void *ptr = qmem_alloc(qm, size); // allocate a size byte memory object
...
qmem_free(qm, ptr); // dealocate a memory object
...
qmem_destruct(qm); 
  // If there are non-dealocated memory objects,
  // all of them are dealocated.

*** Assumption

- Allocation/deallocation may be FIFO manner
  (first allocate, first dealocation).
- Many allocation/deallocation are occured.

*** Restriction

All functions except qmem_free() must called by one thread (called 
master thread).  Othre threads (called worker threads) can not allocate 
qmem.  Under the restriction, qmem doesn't need any locks.
