I/O operations

Notes on common parameters:

handle is the connected endpoint that will be used for I/O.

buf is the buffer to write from or receive into.

len is the number of bytes to transfer.

The timeout parameter in the following methods indicates how long to blocking trying to transfer data. If timeout == 0, then the call behaves as a normal send/recv call, i.e., for blocking sockets, the call will block until action is possible; for non-blocking sockets, EWOULDBLOCK will be returned if no action is immediately possible.

If timeout != 0, the call will wait until the relative time specified in *timeout elapses.

The "_n()" I/O methods keep looping until all the data has been transferred. These methods also work for sockets in non-blocking mode i.e., they keep looping on EWOULDBLOCK. timeout is used to make sure we keep making progress, i.e., the same timeout value is used for every I/O operation in the loop and the timeout is not counted down.

The return values for the "*_n()" methods match the return values from the non "_n()" methods and are specified as follows:

  • On complete transfer, the number of bytes transferred is returned.
  • On timeout, -1 is returned, errno == ETIME.
  • On error, -1 is returned, errno is set to appropriate error.
  • On EOF, 0 is returned, errno is irrelevant.

On partial transfers, i.e., if any data is transferred before timeout / error / EOF, bytes_transferred> will contain the number of bytes transferred.

Methods with iovec parameter are I/O vector variants of the I/O operations.

Methods with the extra flags argument will always result in send getting called. Methods without the extra flags argument will result in send getting called on Win32 platforms, and write getting called on non-Win32 platforms.

ACE_UINT32 ACE::crc32 ( const char *  str)

Computes the ISO 8802-3 standard 32 bits CRC for the string.

bool  close_all_handles = ACE_DEFAULT_CLOSE_ALL_HANDLES,
const ACE_TCHAR  program_name[] = ACE_TEXT ("<unknown>") 
)

Become a daemon process using the algorithm in Richard Stevens "Advanced Programming in the UNIX Environment." If close_all_handles is non-zero then all open file handles are closed.

void ACE::debug ( bool  onoff)
const ACE_TCHAR * ACE::dirname ( const ACE_TCHAR pathname,
ACE_TCHAR  delim = ACE_DIRECTORY_SEPARATOR_CHAR 
)

Returns the "dirname" of a pathname. For instance, the dirname of "/tmp/foo.cpp" is "/tmp" when delim is '/'. If pathname has no delim ".\0" is returned. This method does not modify pathname and is not reentrant.

int ACE::enter_recv_timedwait ( ACE_HANDLE  handle,
const ACE_Time_Value timeout,
int &  val 
)

Wait for timeout before proceeding to a recv operation. val keeps track of whether we're in non-blocking mode or not.

int ACE::enter_send_timedwait ( ACE_HANDLE  handle,
const ACE_Time_Value timeout,
int &  val 
)

Wait for timeout before proceeding to a send operation. val keeps track of whether we're in non-blocking mode or not.

const ACE_TCHAR * ACE::execname ( const ACE_TCHAR pathname)

On Windows, determines if a specified pathname ends with ".exe" (not case sensitive). If on Windows and there is no ".exe" suffix, a new ACE_TCHAR array is allocated and a copy of pathname with the ".exe" suffix is copied into it. In this case, the caller is responsible for calling delete [] on the returned pointer.

Parameters:
pathnameThe name to check for a proper suffix.
Return values:
@cpathname if there is a proper suffix for Windows. This is always the return value for non-Windows platforms.
Ifa suffix needs to be added, returns a pointer to new[] allocated memory containing the original pathname plus a ".exe" suffix. The caller is responsible for freeing the memory using delete [].
int ACE::fini ( void  )

Finalize the ACE library services and releases ACE's internal resources. In general, do not instantiate ACE classes or call methods on objects of these classes after ACE::fini() has been called.

Returns:
Returns 0 on success, -1 on failure, and 1 if it had already been called.
pid_t ACE::fork ( const ACE_TCHAR program_name = ACE_TEXT ("<unknown>"),
int  avoid_zombies = 0 
)

if avoid_zombies == 0 call ACE_OS::fork directly, else create an orphan process that's inherited by the init process; init cleans up when the orphan process terminates so we don't create zombies. Returns -1 on failure and either the child PID on success if avoid_zombies == 0 or 1 on success if avoid_zombies != 0 (this latter behavior is a known bug that needs to be fixed).

size_t ACE::format_hexdump ( const char *  buffer,
size_t  size,
ACE_TCHAR obuf,
size_t  obuf_sz 
)

Format buffer into printable format. This is useful for debugging.

Format buffer into printable format. This is useful for debugging. Portions taken from mdump by J.P. Knight (J.P.Knight@lut.ac.uk) Modifications by Todd Montgomery.

const ACE_TCHAR hostname = 0,
ACE_UINT32  host_addr = 0,
ACE_HANDLE  handle = ACE_INVALID_HANDLE 
)

Get our broadcast address based on our host_addr. If hostname is non-0 we'll use it to determine our IP address. If handle is not ACE_INVALID_HANDLE then we'll use this to determine our broadcast address, otherwise we'll have to create a socket internally (and free it). Returns -1 on failure and 0 on success.

int ACE::get_flags ( ACE_HANDLE  handle) [inline]

Return the current setting of flags associated with handle.

int ACE::get_fqdn ( ACE_INET_Addr const &  addr,
char  hostname[],

ACE_INET_Addr *&  addr_array 
)

Return count and array of all configured IP interfaces on this host, rc = 0 on success (count == number of interfaces else -1). Caller is responsible for calling delete [] on addr_array.

int ACE::get_temp_dir ( ACE_TCHAR buffer,
size_t  buffer_len 
)

Returns the temporary directory including the trailing slash in buffer. Returns -1 for an error or if the buffer_len is not long enough.

ACE_HANDLE ACE::handle_timed_complete ( ACE_HANDLE  listener,
const ACE_Time_Value timeout,
int  is_tli = 0 
)

Wait up to timeout amount of time to complete an actively established non-blocking connection. If is_tli is non-0 then we are being called by a TLI wrapper (which behaves slightly differently from a socket wrapper).

const ACE_TCHAR name,
int  flags,
int  perms,
LPSECURITY_ATTRIBUTES  sa = 0

This function will add appropriate suffix (e.g., .dll on Win32 or .so on UNIX) according to the OS platform. In addition, this function will apply the appropriate prefix (e.g., "lib" on UNIX and "" on Win32) if the filename doesn't match directly.

int ACE::terminate_process ( pid_t  pid)

Terminate the process abruptly with id pid. On Win32 platforms this uses {TerminateProcess} and on POSIX platforms is uses {kill} with the -9 (SIGKILL) signal, which cannot be caught or ignored.

void ACE::unique_name ( const void *  object,
ACE_TCHAR name,
size_t  length 
) [inline]

This method uses process id and object pointer to come up with a machine wide unique name. The process ID will provide uniqueness between processes on the same machine. The "this" pointer of the {object} will provide uniqueness between other "live" objects in the same process. The uniqueness of this name is therefore only valid for the life of {object}.

bool ACE::wild_match ( const char *  s,
const char *  pattern,
bool  case_sensitive = true,
bool  character_classes = false 
)

Simple wildcard matching function supporting '*' and '?' return true if string s matches pattern. If character_classes is true, '[' is treated as a wildcard character as described in the fnmatch() POSIX API.

const void *  buf,
size_t  len,
size_t *  bytes_transferred = 0 
) [inline]

Receive into a variable number of pieces.

Accepts a variable, caller-specified, number of pointer/length pairs. Arguments following n are char *, size_t pairs.

Parameters:
handleThe I/O handle to receive on
nThe total number of char *, size_t pairs following n.
Returns:
-1 on error, else total number of bytes received.
ssize_t ACE::write_n ( ACE_HANDLE  handle,
const ACE_Message_Block message_block,
size_t *  bytes_transferred = 0 
)

Write all the message_blocks chained through their next and cont pointers. This call uses the underlying OS gather-write operation to reduce the domain-crossing penalty.

ssize_t ACE::writev_n ( ACE_HANDLE  handle,
const iovec *  iov,
int  iovcnt,
size_t *  bytes_transferred = 0 
)

Receive into a variable number of pieces.

Accepts a variable, caller-specified, number of pointer/length pairs. Arguments following n are char *, size_t pairs.

Parameters:
handleThe I/O handle to receive on
nThe total number of char *, size_t pairs following n.
Returns:
-1 on error, else total number of bytes received.

Variable Documentation

unsigned int ACE::init_fini_count_ = 0

Counter to match <init()>/<fini()> calls. <init()> must increment it; <fini()> must decrement it. <fini()> then does nothing until it reaches 0.

size_t ACE::pagesize_ = 0
