ACE_POSIX_SIG_Asynch_Transmit_File(3)

NAME

ACE_POSIX_SIG_Asynch_Transmit_File -

This class implements ACE_Asynch_Transmit_File for Real-Time Signal (sigtimedwait) based implementation of Proactor.

SYNOPSIS

class ACE_POSIX_SIG_Asynch_Transmit_File : 
  public virtual ACE_Asynch_Transmit_File_Impl,
  public ACE_POSIX_SIG_Asynch_Operation
{
  public:
    ACE_POSIX_SIG_Asynch_Transmit_File (
        ACE_POSIX_SIG_Proactor *posix_sig_proactor
        );
    int transmit_file (
        ACE_HANDLE file,
        ACE_Asynch_Transmit_File::Header_And_Trailer *header_and_trailer,
        u_long bytes_to_write,
        u_long offset,
        u_long offset_high,
        u_long bytes_per_send,
        u_long flags,
        const void *act,
        int priority,
        int signal_number
        );
    virtual ~ACE_POSIX_SIG_Asynch_Transmit_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;
};

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
    );

Initializes the factory with information which will be used with each asynchronous call. If (handle == ACE_INVALID_HANDLE), ACE_Handler::handle will be called on the handler to get the correct handle.

int cancel (void);

@@ Not implemented. Returns 0.

ACE_Proactor* proactor (void) const;

Return the underlying proactor.
