Performs a read/write operation on a named pipe
#include <NamedPipes.au3>
_NamedPipes_CallNamedPipe ( $sPipeName, $pInpBuf, $iInpSize, $pOutBuf, $iOutSize, ByRef $iRead [, $iTimeOut = 0] )
$sPipeName | Pipe name |
$pInpBuf | Pointer to the buffer containing the data written to the pipe |
$iInpSize | Size of the write buffer, in bytes |
$pOutBuf | Pointer to the buffer that receives the data read from the pipe |
$iOutSize | Size of the read buffer, in bytes |
$iRead | On return, contains the number of bytes read from the pipe |
$iTimeOut | [optional] Number of milliseconds to wait for the named pipe to be available. In addition to numeric values, the following special values can be specified: -1 - Wait indefinitely 0 - Uses the default time-out specified in the call to the CreateNamedPipe 1 - Do not wait. If the pipe is not available, return an error |
Success: | True. |
Failure: | False. |
Calling CallNamedPipe is equivalent to calling the CreateFile (or WaitNamedPipe, if CreateFile cannot open the pipe immediately), TransactNamedPipe, and CloseHandle functions.
CreateFile is called with an access flag of GENERIC_READ | GENERIC_WRITE, and an inherit handle flag of False.
CallNamedPipe fails if the pipe is a byte-type pipe.
