## Constructor & Destructor Documentation

ACE_Reactive_MEM_IO::~ACE_Reactive_MEM_IO | ( | void |  | ) | `[virtual]`

## Member Function Documentation

ASYS_INLINE ssize_t ACE_Reactive_MEM_IO::get_buf_len | ( | const off_t | off,
|  | ACE_MEM_SAP_Node *& | buf
| ) |

| Convert the buffer offset <off> to absolute address to <buf>. Return the size of valid information containing in the <buf>, -1 if <shm_malloc_> is not initialized.

int ACE_Reactive_MEM_IO::init | ( | ACE_HANDLE | handle,
|  | const ACE_TCHAR * | name,
|  | MALLOC_OPTIONS * | options
| ) | `[virtual]`

| Initialize the MEM_SAP object. options is used to pass in the Malloc_Options to initialize underlying ACE_MMAP. Implements ACE_MEM_SAP.

ssize_t ACE_Reactive_MEM_IO::recv_buf | ( | ACE_MEM_SAP_Node *& | buf,
|  | int | flags,
|  | const ACE_Time_Value * | timeout
| ) | `[virtual]`

| Fetch location of next available data into <recv_buffer_>. As this operation read the address of the data off the socket using ACE::recv, <timeout> only applies to ACE::recv. Implements ACE_MEM_SAP.

ssize_t ACE_Reactive_MEM_IO::send_buf | ( | ACE_MEM_SAP_Node * | buf,
|  | int | flags,
|  | const ACE_Time_Value * | timeout
| ) | `[virtual]`

| Wait to to <timeout> amount of time to send <buf>. If <send> times out a -1 is returned with <errno == ETIME>. If it succeeds the number of bytes sent is returned. Implements ACE_MEM_SAP.
