Function Documentation

psPtr psMemDecrRefCounter (  psPtr  ptr  )

Decrement reference counter and return the pointer. Returns: psPtr the pointer deremented in refCount, or NULL if pointer is fully dereferenced. Parameters: ptr  Pointer to decrement refCounter, and return

psReferenceCount psMemGetRefCounter (  const psPtr  ptr  )

Return reference counter. Returns: psReferenceCount Parameters: ptr  Pointer to get refCounter for

psPtr psMemIncrRefCounter (  const psPtr  ptr  )

Increment reference counter and return the pointer. Returns: psPtr Parameters: ptr  Pointer to increment refCounter, and return

psPtr psMemSetRefCounter (  psPtr  ptr, psReferenceCount  count )

Set reference counter and return the pointer. Returns: psPtr the pointer with refCount set, or NULL if pointer is fully dereferenced. Parameters: ptr  Pointer to decrement refCounter, and return count  New reference count
