BOOL PChannel::Write ( const void *  buf,
PINDEX  len 
) [virtual, inherited]

Low level write to the channel. This function will block until the requested number of characters are written or the write timeout is reached. The GetLastWriteCount() function returns the actual number of bytes written.

The GetErrorCode() function should be consulted after Write() returns FALSE to determine what caused the failure.

Returns:
TRUE if at least len bytes were written to the channel.
Parameters:
buf  Pointer to a block of memory to write.
len  Number of bytes to write.

Reimplemented in PDelayChannel, PRFC822Channel, PInternetProtocol, PMemoryFile, PSSLChannel, PWAVFile, PQueueChannel, PTelnetSocket, PEthSocket, PFile, PIndirectChannel, PPipeChannel, PStructuredFile, PSoundChannel, PTCPSocket, PUDPSocket, and PVideoChannel.
