share_buffer_with - allow another process to map a shareable buffer

#include <SharedBuffer.h>

int share_buffer_with(int shared_buffer_id, pid_t peer_pid);

Gives the process with PID peer_pid permission to map the shareable buffer with ID shared_buffer_id.

On success, returns 0. Otherwise, returns -1 and errno is set.

EINVAL: peer_pid is invalid, or shared_buffer_id is not a valid ID.
EPERM: The calling process does not have access to the buffer with shared_buffer_id.
ESRCH: No process with PID peer_pid is found.
