Member Function Documentation

ssize_t ACE_Reactive_MEM_IO::get_buf_len ( const ACE_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,

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 

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 

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.
