| typedef struct rtl_cache_st rtl_cache_type |
Opaque rtl_cache_type.
| SAL_DLLPUBLIC void* rtl_allocateAlignedMemory | ( | sal_Size | Alignment, |
| sal_Size | Bytes | ||
| ) |
Allocate aligned memory.
A call to this function will return NULL upon the requested memory size being either zero or larger than currently allocatable.
Memory obtained through this function must be freed with rtl_freeAlignedMemory.
| Alignment | [in] alignment in bytes, must be a power of two multiple of sizeof(void*). |
| Bytes | [in] memory size. |
| SAL_DLLPUBLIC void* rtl_allocateMemory | ( | sal_Size | Bytes | ) |
Allocate memory.
A call to this function will return NULL upon the requested memory size being either zero or larger than currently allocatable.
| Bytes | [in] memory size. |
| SAL_DLLPUBLIC void* rtl_allocateZeroMemory | ( | sal_Size | Bytes | ) |
Allocate and zero memory.
A call to this function will return NULL upon the requested memory size being either zero or larger than currently allocatable.
| Bytes | [in] memory size. |
| SAL_DLLPUBLIC void* rtl_arena_alloc | ( | rtl_arena_type * | pArena, |
| sal_Size * | pBytes | ||
| ) |
| pArena | [in] arena from which resource is allocated. |
| pBytes | [inout] size of resource to allocate. |

| pName | [in] descriptive name; for debugging purposes. |
| quantum | [in] resource allocation unit / granularity; rounded up to next power of 2. |
| quantum_cache_max | [in] max resources to cache; rounded up to next multiple of quantum; usually 0. |
| source_arena | [in] passed as argument to source_alloc, source_free; usually NULL. |
| source_alloc | [in] function to allocate resources; usually rtl_arena_alloc. |
| source_free | [in] function to free resources; usually rtl_arena_free. |
| nFlags | [in] flags; usually 0. |
| SAL_DLLPUBLIC void rtl_arena_destroy | ( | rtl_arena_type * | pArena | ) |
| SAL_DLLPUBLIC void rtl_arena_free | ( | rtl_arena_type * | pArena, |
| void * | pAddr, | ||
| sal_Size | nBytes | ||
| ) |
| pArena | [in] arena from which resource was allocated. |
| pAddr | [in] resource to free. |
| nBytes | [in] size of resource. |
| SAL_DLLPUBLIC void* rtl_cache_alloc | ( | rtl_cache_type * | pCache | ) |
| pCache | [in] cache from which object is allocated. |

| int | nFlags | ||
| ) |
| pName | [in] descriptive name; for debugging purposes. |
| nObjSize | [in] object size. |
| nObjAlign | [in] object alignment; usually 0 for suitable default. |
| constructor | [in] object constructor callback function; returning 1 for success or 0 for failure. |
| destructor | [in] object destructor callback function. |
| reclaim | [in] reclaim callback function. |
| pUserArg | [in] opaque argument passed to callback functions. |
| pSource | [in] opaque argument passed to callback functions. |
| nFlags | [in] flags. |
| SAL_DLLPUBLIC void rtl_cache_destroy | ( | rtl_cache_type * | pCache | ) |
| SAL_DLLPUBLIC void rtl_cache_free | ( | rtl_cache_type * | pCache, |
| void * | pObj | ||
| ) |
| pCache | [in] cache from which object was allocated. |
| pObj | [in] object to free. |
| SAL_DLLPUBLIC void rtl_freeAlignedMemory | ( | void * | Ptr | ) |
Free memory allocated with rtl_allocateAlignedMemory.
| Ptr | [in] pointer to previously allocated memory. |
| SAL_DLLPUBLIC void rtl_freeMemory | ( | void * | Ptr | ) |
Free memory.
| Ptr | [in] pointer to previously allocated memory. |
| SAL_DLLPUBLIC void rtl_freeZeroMemory | ( | void * | Ptr, |
| sal_Size | Bytes | ||
| ) |
Zero and free memory.
| Ptr | [in] pointer to previously allocated memory. |
| Bytes | [in] memory size. |
| SAL_DLLPUBLIC void* rtl_reallocateMemory | ( | void * | Ptr, |
| sal_Size | Bytes | ||
| ) |
Reallocate memory.
A call to this function with parameter 'Ptr' being NULL is equivalent to a rtl_allocateMemory() call. A call to this function with parameter 'Bytes' being 0 is equivalent to a rtl_freeMemory() call.
| Ptr | [in] pointer to previously allocated memory. |
| Bytes | [in] new memory size. |
| SAL_DLLPUBLIC void rtl_secureZeroMemory | ( | void * | Ptr, |
| sal_Size | Bytes | ||
| ) |
Zero memory.
Fills a block of memory with zeros in a way that is guaranteed to be secure
| Ptr | [in] pointer to previously allocated memory. |
| Bytes | [in] memory size. |
