	##//filenum//##
		A file number bound to an ##[[KeyPgOpenTcp|Open Tcp]]## connection or an accepted TCP client.

{{fbdoc item="ret"}}
	Returns true (-1) if the connection has ended, zero (0) otherwise.

{{fbdoc item="desc"}}
	##**Eoc**## means "end of connection".  It is intended for TCP file numbers, where ##[[KeyPgEof|Eof]]## only says that no byte is immediately available to read.  A TCP program can poll ##Eof## to decide whether a read is ready and ##Eoc## to decide whether the remote endpoint has closed the socket.

	Calling ##**Eoc**## on a non-TCP file number is an illegal function call.
