|
- Parameters
-
size | The number of bytes to allocate |
- Returns
- A pointer to the allocated memory block or NULL on failure

nmemb | The number of elements to allocate |
size | The size in bytes of each element |
- Returns
- A pointer to the allocated memory block or NULL on failure
◆ osa_realloc()
void* osa_realloc |
( |

ptr, |
|
|
size_t |
size |
|
) |
| |
- Parameters
-
ptr | The existing memory block |
size | The size of the new memory block |
- Returns
- A pointer to the allocated memory block or NULL on failure

|
) |
| |
Copy from one memory area to another where the areas do not overlap
- Parameters
-
dest | The destination pointer |
src | The source pointer |
n | Number of bytes to copy |
- Returns
- A pointer to dest

|
) |
| |
- Parameters

( |
void * |
dest, |
|
|
const void * |
src, |
|
|
size_t |
n |
|
) |
| |
Copy from one memory area to another. Copying takes place as though the bytes in src are first copied into a temporary array that does not overlap src or dest, and the bytes are then copied from the temporary array to dest.
- Parameters
-
dest | The destination pointer |
src | The source pointer |
n | Number of bytes to copy |
- Returns
- A pointer to dest

|
uint32_t |
type |
|
) |
| |
Use this API to set the allocating memory block's owner. This API should be called after succeeding to allocate memory.
- Parameters
-
ptr | The existing memory block |
type | The module type of this memory block's owner |
- Return values
-
TRUE | : success |
FALSE | failure |
