ACE_POSIX_AIOCB_Asynch_Write_File(3)

NAME

ACE_POSIX_AIOCB_Asynch_Write_File -

This class provides concrete implementation for ACE_Asynch_Write_File for POSIX platforms where the completion strategy for Proactor is based on AIOCB (AIO Control Blocks).

SYNOPSIS

class ACE_POSIX_AIOCB_Asynch_Write_File : 
  public virtual ACE_Asynch_Write_File_Impl,
  public ACE_POSIX_AIOCB_Asynch_Write_Stream
{
  public:
    ACE_POSIX_AIOCB_Asynch_Write_File (
        ACE_POSIX_AIOCB_Proactor *posix_aiocb_proactor
        );
    int write (
        ACE_Message_Block &message_block,
        u_long bytes_to_write,
        u_long offset,
        u_long offset_high,
        const void *act,
        int priority,
        int signal_number = 0
        );
    virtual ~ACE_POSIX_AIOCB_Asynch_Write_File (void);
    int open (
        ACE_Handler &handler,
        ACE_HANDLE handle,
        const void *completion_key,
        ACE_Proactor *proactor = 0
        );
    int cancel (void);
    ACE_Proactor* proactor (void) const;
  private:
    int write (
        ACE_Message_Block &message_block,
        u_long bytes_to_write,
        const void *act,
        int priority,
        int signal_number = 0
        );
};

DESCRIPTION

The implementation classes for POSIX implementation of Asynch Operations are defined here in this file.

Methods belong to ACE_POSIX_Asynch_Operation base class. These

methods are defined here to avoid dominace warnings. They route the call to the ACE_POSIX_Asynch_Operation base class.

int open (
    ACE_Handler &handler,
    ACE_HANDLE handle,
    const void *completion_key,
    ACE_Proactor *proactor = 0
    );

int cancel (void);

ACE_Proactor* proactor (void) const;
