## Name
|
||
|
|
|
||
|
|
shbuf\_create - create a shareable memory buffer
|
||
|
|
|
||
|
|
## Synopsis
|
||
|
|
```**c++
|
||
|
|
#include <SharedBuffer.h>
|
||
|
|
|
||
|
|
int shbuf_create(int size, void** buffer);
|
||
|
|
```
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
Creates a new memory region that can be shared with other processes. The region is only accessible to the calling process by default.
|
||
|
|
|
||
|
|
## Return value
|
||
|
|
|
||
|
|
If a region is successfully created, `shbuf_create()` stores a pointer to the memory in `buffer` and returns a buffer ID. Otherwise, it returns -1 and sets `errno` to describe the error.
|
||
|
|
|
||
|
|
## Errors
|
||
|
|
|
||
|
|
* `EINVAL`: `size` is zero or negative.
|
||
|
|
* `EFAULT`: `buffer` is not a valid address.
