Macros

#define OSAPI_ALIGNMENT_DEFAULT   (-1)
 Certain methods allow a default alignment: this should be an alignment that follows the "malloc" alignment of the architecture (aligned sufficiently to store any C-structure efficiently).

Typedefs

typedef RTI_INT32 OSAPI_Alignment_T
 The OSAPIAlignment is the alignment in bytes; an address is aligned when it is a positive integer multiple of the alignment.

Functions

void * OSAPI_Heap_allocate (RTI_INT32 count, RTI_INT32 size)
 Allocates zero-initialized memory from the heap.
void OSAPI_Heap_free (void *ptr)
 Frees memory allocated from the heap.
void OSAPI_Heap_allocate_struct (TYPE **pointer, TYPE)
 Allocates space on the heap for a C structure and initializes the structure with 0's.
void OSAPI_Heap_free_struct (TYPE *pointer)
 Returns previously allocated (with OSAPI_Heap_allocate_struct) space to the heap.
void OSAPI_Heap_allocate_array (TYPE **pointer, int count, TYPE)
 A static method to allocate space on the heap for an array of C structures; the array is initialized with 0's.
void OSAPI_Heap_free_array (TYPE *storage)
 A static method to return space (that was previously allocated with OSAPI_Heap_allocate_array) to the heap.
void OSAPI_Heap_allocate_string (char **pointer, RTI_UINT32 size)
 A static method to allocate space on the heap for a string of up to a given size. The string is initialized with 0's.
void OSAPI_Heap_free_string (char *pointer)
 A static method to return space string space to the heap.
void OSAPI_Heap_allocate_buffer (char **buffer, RTI_UINT32 size, OSAPI_Alignment_T alignment)
 A static method to allocate a block of memory of the provided size from the heap.
void OSAPI_Heap_free_buffer (void *buffer)
 A static method to return a block (that was previously allocated with OSAPI_Heap_allocate_buffer) to the heap.
RTI_SIZE_T OSAPI_Heap_get_allocated_byte_count (void)
 Return current allocated memory.

Variables

RTI_SIZE_T OSAPI_gv_AllocatedByteCount
 Current allocated bytes.
